Xiom Jekyll & Hyde 47.5 V Weight: 70 grams uncut Speed: off++ Spin: Very high 47.5 X Weight: 68 grams uncut Speed: off+ Spin: Very high 












The Jekyll & Hyde series rubbers are the newest
addition to the Xiom line this year. I believe this is the newest generation
among ESN rubbers in the market today. There are lots of variants for the
Jekyll & Series and to be honest it took me a while to fully review all
rubbers since I have both 2.1mm and max thickness rubbers of each variant. I
think I have a total of 2 dozen+ rubbers received. The Jekyll & Hyde rubbers
have quite a strange name for the series. Believe me, I was surprised when Xiom
choose the name since it is quite far from the usual nomenclature for their
rubbers which are mostly taken from the Greek alphabet. I tested the 47.5 X and
V versions with the TMXi and Hugo HAL among other blades that I usually use.
Let me just say that some of the ratings that XIom is showing, I will not
agree. I do not agree that the Jekyll & Hyde rubbers are faster than some
of the Omega VII rubbers especially the Hyper and Tour versions. What I have
experienced is different. Based on my opinion, Xiom has designed rubbers
specific for specific type of play. The Jekyll & Hyde series has more
variants compared to the Omega series. It is not just developing rubbers that
are faster and spinnier but for Xiom’s design time, they opted to have rubbers that
fairly easy to use compared to the Omega 7 rubbers that have released before. Both the J&H 47 X and V versions are offensive
rubbers. These are fast rubbers and to a certain degree, both the X and V
versions are both faster than the Omega 7 Pro and Euro rubbers. They seem to
have the same technology and sponge but rather differ in the design. I would
rate the J&H V version to be faster than the X. You can feel the difference
in speed if you use both in the same blade. Since the grip of the rubbers are
more on the grippy and not tacky side, I choose to have the topspin shots that
engage more of the sponge. By compressing more of the sponge, you will
appreciate the speed of both 47.5 J&H variants. Coincidentally, up to a
certain amount of sponge compression, the 47.5 rubbers are easier to increase
or pick up speed compared to their harder variants. I also think the longer pip
structure of the 47.5 X and V rubbers greatly help with the speed. I would put
the speed of the 47.5 both versions to be slightly faster than the Evolution
MX-P rubber. The 47.5 V is both better than the 47.5 X in terms of active
blocking and smashing due to having less spin sensitivity. The 47.5X on the
other hand is much better on spin drives and counter topspins. Both the 47.5
variants have the least spin sensitivity among all other J&H rubbers. The J&H 47.5 X version is the spinnier one between
the 2 variants. The topsheet is very grippy but it is not tacky at all. Most of
the proper spin generation for both rubbers is that the sponge compression is
needed instead of thinly brushing the ball. The topsheet having longer pip
structure compared to other J&H variants, helps the ball sink more and also
let the topsheet increase the surface area of the ball being grabbed by both
topsheet and sponge. The arc of the 47.5 X is more profound compared to the
47.5 V and if you need more room for error in clearing the net, the 47.5 X is
the rubber you need to choose to loop better. The lower arc of the 47.5 V is
better for players who have opted for a low and sharp arc loop. For short strokes, I have not noticed much the
difference. For pushes for example, both seem to be equally spinny only that
the 47.5V is somewhat a little faster. For drop shots, both are almost the
same. I would recommend both 47.5 variants as a great replacement with the MX-P
since the topsheet looks more durable and with the improved sponge technology
and booster used, especially the 47.5 X, players who are looking for a
medium-hard rubber will like both rubbers. If I were to choose which should be
the forehand and backhand rubber, I guess the 47.5 X for the forehand and 47.5
V for the backhand. Xiom Jekyll & Hyde 52.5 X, V and Z versions 52.5 V version Weight: 69 grams uncut Speed: off++ Spin: extremely high 52.5 H version Weight: 70 grams uncut Speed: Off+ Spin: Extremely High 52.5 Z version Weight: 72 grams uncut Speed: Off++ Spin: Extremely high 












The Jekyll & Hyde 52.5 Series rubbers are considered
the high-performance rubbers in the series. It would be hard to generalize the
explanation of these rubbers but to simplify their designs would give an
understanding on the specific type of plays and players each of the rubbers are
intended for. In my opinion, Xiom went beyond just simply giving different
kinds of hardness on sponges for players to choose from because it is already a
common practice among ESN-produced rubbers but they took a step further by
designing rubbers that are specific to strokes or types of ball contact that a
certain player has. With these rubbers, you can, choose which variant of the
J&H rubber would be good for you. The topsheets of the Z, V and H variants are slightly
tacky. I cannot consider them as totally grippy because they would stick to the
plastic covers easily unlike the regular Xiom Omega VII Pro or Europe versions.
The are all covered by a wax paper-like material for dust protection when you
open the packaging. The topsheets are very durable as I have been playing with them
for a month now and they are very durable in a way where the topsheet eroding
is not that evident. Not only I play with these rubbers I use them to feed multiball
drills just to test them for durability. I would say the 52.5 Jekyll & Hyde
topsheets seem more durable compared to the Omega VII series. The Omega 7
rubbers are very durable do not get me wrong but the J&H rubbers seem to
have a longer lifespan in the topsheets. So, what are the differences that I have observed during my
tests on these rubbers? The H version seem to be the spinniest if you are
concentrated on just pure looping either late or peak contact. The H version has
the most tack but still less compared to the tackiness that a National H3
rubber has. If you compare the tackiness of the 52.5H with the Omega 7 Guang or
Ying, the Omega 7 C Guang and Ying still has more tack. The V 52.5 version has
the least amount of tacky though it still can be considered as slightly tacky
and not just grippy. The Z version is only slightly less tacky than the H
version. All 3 are spinnier than Tenergy 05. I can feel like I am using almost
a Chinese rubber when looping or doing spinny pushes. Overall performance of each rubber including speed, the V
version is the fastest among the 3 52.5 variants while the H is the slowest and
Z version seem to be in between. Although the Z version and the H version have
the same speed rating according to Xiom, the Z version seem to have a little
bit more in speed. I am biased towards
the H version because the arc is more profound compared to the Z version and V
version. V version has the lowest arc but the fastest in terms of speed. The H
version is easier to use if you will be asking me and that is the reason why I
like it very much. The Z version was made for higher level players. Although
the H version is designed to be the spinniest, in terms of combination of power
and spin, my money is on the Z version. The Z version was designed to be like a
less tacky Hurricane 3 National version but has more speed and sponge response.
The Z version when being used with stronger sponge compression, i.e., hitting
through the sponge more due to stronger swings, the Z version can outperform
the V and H versions with the combination of power and spin it can produce. The
Z version although less spinnier than H version has the most kick when the ball
lands into the table after you hit with a heavy topspin. In terms of blocking
and spin sensitivity, the V version is the best among the 3 and with the H
performing the least in this department. I would attribute the slightly longer
pip structure of the V version for its extra kick. The Z and H versions have a
shorter pip structure but somewhat have a thicker upper topsheet part. I think
this design gives them better ability in brushing the ball during topspins and
push chops and to some extend doing spinny serves. As what I have discussed, the Z version is better for
advanced players. It was not designed to be the fastest but for advanced
players who can hit more and stronger, only this rubber can be fully utilized.
I think it was designed to have a stronger effect if the player has better
control when using full swings at higher levels of play. The performance of the
Z version is on its balance of speed and spin. These 2 factors are in my
opinion the 2 variables that companies have a hard time developing. You can
develop very spinny and tacky rubbers that are spinnier than Hurricane 3 rubbers
but it will cost you in the speed department. You can develop very grippy
rubbers but in modern times, if you want an extra amount of spin, tackiness can
add to that spin a bit more. Speed can easily be produced because it is less
tricky to produce fast and very bouncy sponges but then again, speed is not
everything and you would need it to balance with the ability to spin the ball
the moment it touches the surface of the topsheet. The V version for me is better
for players who hits more and do spin drive more than loops. Although it is
already very spinny, I think it is much better to drive and smash with it. If
you spin more, loop more and not a top- level player, the H version is more
than enough. It has the spin and speed that an advanced player needs. If you are
more into slower but spinny loops, the H version is the rubber for you. The H
version is the rubber for any spinny shot inside or outside the table. Whether
it is for late contact loops or for drop shots, the H version does that for
you. Jekyll & Hyde 50X Weight: 70 grams uncut Speed: Off+ Spin: Extremely High 




To be honest this
is my most favorite Jekyll & Hyde rubbers. It is easily controllable
despite being fast and spinny. At first, I was a bit confused with the design
of the 50X. It is the slowest among the J&H rubbers (this rubber is still
fast compared to many rubbers) and also not the spinniest but the more you use
it, it grows on you more and it is easier to produce spinny shots and power
shots with the 50X. I think for most of the players I have given this rubber to
or people who have tried it, all of them were really impressed by the spin and
at the same time they all mentioned that it was easier to use than Tenergy 05
or 05fx. Despite having a 50-degree sponge hardness, there some sort of
softness due to the combination of the topsheet and sponge that let the ball
sinks into rubber easily. It is slightly tacky but the spin generation for the
Jekyll & Hyde 50X is more suited to a sponge compression + brushing to
produce a heavy amount of spin. It has this characteristic during loop that the
ball suddenly springs into action that the moment you compress and brush it in
the sponge, the ball speed kicks in and it has this very spinny kick when it
lands on the table. If compared to other rubbers, it has less sharpness in
angle due to a more profound medium arc. It would say the sponge and playing characteristic of the
J&H 50X borrows some sponge bounciness from the 47.5 X version but offers
more spin due to its slightly tacky surface. The speed is fast but it is not faster
than the 47.5V version which on a certain amount of compression is the fastest
among the series. I would say the 50X is slightly faster than the Omega 7 Asia.
People would think that the O7 Asia is fast but it has this sponge that is not
as reactive compared to the Guang or O7 Tour making the Omega 7 Asia more
controllable. It acts more like a hybrid rubber that is very springy and at the
same time spinny. I think the control and accuracy of the 50X is the best among
the J&H variants and I wonder if it will have the H and Z versions, I think
it will be much more awesome. Up to this point, these are the only versions of
the J&H rubbers but no C version or H version for the 50 and no Z or C
version for the 47.5 variants. The C version and V version are the ones missing
in the 52.5-degree version but I think the V version is not needed anymore
since they have the X version already. Why the 50X has no V version yet? I can
only speculate that when you have harder rubbers on 50 degrees hardness and
above, there are balancing acts that you would have to make like not neglecting
the spin, either you make the topsheet very grippy and somewhat soft to make
the ball sink easier and then have the topsheet and sponge wrap around the ball
better or make the topsheet a little tacky. I can guarantee most tenergy users
here whether you are using the FX or regular 05 version, the 50X is much
spinnier and has more kick into it with the sponge. Whether we admit it or not,
the Tenergy 05 rubbers lost some amount of spin when the ball changed over to
40+ poly. Nowadays there are lost of Euro rubbers that you can considere to be
spinnier than Tenergy 05. Yes, you might say it is still the spinniest for you
but that is because you have used that for a long time and you are already
accustomed to it but there are new rubbers today that has better and easier
playing characteristics.
As I end this review, it is my opinion that the rubbers
of today have reached a somewhat plateau in terms of spin generation because
the improvement in the spin department seem not that much. I am mostly pointing
out to Euro and Japan rubbers. Each company would just have to finely tune
their rubber designs to get the most spin improvement while maintaining the
speed. The Chinese rubbers have the best spin but the sponges heavily dependent
on tuners. Maybe due to keeping the prices lower, the Chinese companies do not
produce super-fast sponges. You will see companies like Xiom to further improve
the present rubbers that even a small percentage of increase would already be
good. To put it on a much simpler explanation, it is like a car in formula 1.
There are restrictions on the engine and other specs and you would have to fine
tune everything to have just even 1% increase in performance, that would
already be great.
