Yes, he's using Superwall OX on the OSP Immune OX blade. I've never played with Superwall, but I play with the Immune OX. It's a combo blade--slow, hard BH side--ideal for OX LP--and a softer, faster attacking (FH) side. It is, quite simply, the best combo blade I've ever used. So perfectly consistent on both sides, massive sweet spot and lovely dwell time on the FH and total control on the BH. AS well as the control on the BH side, however, it seems to add wobble to the ball and definitely gives better reverse spin on blocks than any other defensive blades I've used with LPs. (Donic Senso, Hallmark Aurora, Hallmark Combo). The blade is handmade in Hungary and you can choose your own handle and from 3 different blade face sizes. Not cheap but not outrageous either for the best blade I've ever owned.

Now I'm using Spinlord Agenda OX for chopping distant from the table but I have experience with neptune 0.7 mm.
The difference I noticed:
Agenda OX -> easier to control, huge reversal, deception
Neptune 0.7 mm -> amazing undercut spin when chopping, high reversal

IMHO as traditional defense sponged lps are for skilled hands...

I prefer playing against OX to playing against sponge. With OX, the returns are very predictable - usually dead or reversal.  With sponge, there is this element of need to know whether your opponent is adding to the spin, taking off the spin, passing through the spin or killing the spin so you have to watch the ball closely to tell how much spin is still left or whether your opponent really took anything off.
I like putting heavy topspin on the ball...

I tried both OX and 1.0 Yasaka Phantom in the backhand of my cpen bat.
Found OX better only to receive serves. The sponged version is better in everything else, chopping, hitting and disturbing opponents. It also brought the perfect balance to my blade. With OX pips it was like I was using only one rubber.

So I must conclude that the spongy rubbers will move the ball faster because of the mass of the total.
I also like the 563 mp for fun.
thank you kindly.
You need to look at the speed after impact formula half way down the page.
http://en.wikipedia.org/wiki/Coefficient_of_restitution
In theory the extra mass will increase the speed after impact but it doesn't increase linearly with the additional mass nor is the mass of the sponge that great relative to the rest of the paddle.
The sponge decreases the COR because it absorbs energy.  This more than offsets the speed increase due to extra mass.

I have played with both 563 0X and 563 1.5mm.   I tried the 563 1.5mm on my Samsonov Alpha and the 563 0X on my Toni Hold White Spot because the THWS is a very slow blade and I needed something slow to absorb the energy of fast incoming balls. I can make the usual stroke through the ball type of strokes resulting in a little reversal or knuckle balls but I find it hard to do anything but flat hit with 563 on the offense.  Better players seem to have no problems playing against the 563.  With 802-40 1.8mm I can put pressure on the opponent by using top spin.  With LP there is the fear, uncertainty and doubt factor do to spin reversal.

563 is interesting to play with for fun but it wouldn't be my first choice in a match.

thanks for all the suggestions; I have my first 15 mins training. It is the underspin service receive with my BH 563. My coach tells me that pimple w/ the sponge or OX for receiving serve is the same thing Wacko

Someone that claims thicker sponges are faster should be able to come up with a proof that doesn't defy the laws of physics.   No one has refuted my claims.

 It doesn't matter the top sheet is pips in or out.
Agreed.

 You can experiment it yourself by buying the same rubber with different sponge thickness, 
I am way ahead of you.  I posted a link to this video a month ago.   I have been too busy traveling and playing TT to do much testing.
http://deltamotion.com/peter/TableTennis/I%20just%20got%20my%20HRS%20sponges.mp4
You can see in the preliminary test the thick sponge does not result in higher bounce.
I need to drop the ball from higher elevations when I get serious.  We have a balcony where I can drop the ball about 5m.

Quote
or you can just think about this: why would pretty much all pro's, except the defenders, use max sponge thickness? Some of them even try to sneak pass the 4mm overall thickness limit, just to absorb more energy and have a slower racket? 
Because they want spin and are willing to give up a little speed to get it.

Also, the claim that modern rubbers are relative fast compared to the blade is false.  I will post a link to this one...more....time.
http://www.ittf.com/ittf_science/SSCenter/docs/199408014%20-%20%20Tiefenbacher%20-%20Impact.pdf
This link has been posted at least a half dozen times but no one seems to understand what they are reading.

Notice the the Epar are normal coefficient of restitution is about 0.6.  ( see page 11 ).   That means the ball will bounce back at about 0.6 of the impact speed when hitting a stationary paddle.  Since the kinetic energy is proportional to the velocity squared that means the ball has about 36% of the energy that it had before impact.   The ball loses 64% of its energy.   
See figure 6 on page 7.  It is clear that the marble covered with rubber is slower than bare marble.   The same goes for the wood.   Adding sponge makes the paddle slower.

If you want to know how fast the ball will bounce back when the paddle is moving then look at the speed after impact area of this link.
http://en.wikipedia.org/wiki/Coefficient_of_restitution
The Tiefenbacher pdf doesn't say how you use the Epar or coefficient of restitution in a calculation.  One uses the speed after impact formulas.

The point is that adding rubber does not make the paddle faster.   The wood and rubber absorb a lot of energy.  Adding more sponge will only absorb more energy.  Now, it is up to you to refute this data and my arguments.

What I find interesting is that the ball impacting on marble COR drops so much at higher speeds.

Certainly the ball can be hit faster with with more sponge if more energy is put into it.  If a little top spin is added then the ball can be hit even faster because now the ball will drop due to the top spin.  ( So how much energy is rotational energy? Where does that come from? )  However, we were talking about using pips and speed.   There is a difference in how you play with the rubber vs the property of the rubber itself.

Hitting a ball for high speed with a bare blade can have a lot more impact for the ball then dropping it or softly bounce on a floor. Much more deformation going with it.
I assume this drops the efficiency for the rebound from side of the ball as weaker (also from shape). Sponge decreases this deformation offcourse. Even if it looses some from the side of the racquet (and player) when it gains more from the balls side the result can still be a gain. Also for the player.
Ox is not a totally bare blade offcourse (balls can even be cracked then) but still.  This type of drop in speed won,t help for control as usual. It,s too much unexpected behavour for that difficult for controlling the ball. With ox on blades that tend to be more harsh on a ball (off+ carbon blades for instance) this will increase. Some sponge (if it,s not an offensive sponge) will therefor be easier when the blade is more an offensive blade. The speed doesn,t increase from a more defensive sponge.
Typical for this (I think) is that on softer allround or defensive blades or also thick soft balsa blades thinner sponge can be faster then max or at least the difference is less then with some hard off+ blades.
The loss from the additional sponge starts to prevail then over the gain because the blade allready has a softness from itself to keep the deformation of the ball lower.

Other reason why a sponge can be easier on offensive blades is that it can help graze more spin from a topspin. That can avoid balls to float long sometimes from a combination of speed and backspin.

But it,s probably better to learn with pips on easier blade and no -sponge.

Modern Defender

Strokes Used:

The modern defender uses backspin as an attacking weapon, to set up his attacks. The typical modern defender uses a shakehand grip, and chops with heavy backspin on the backhand side. On the forehand side, this player will chop the ball when his opponent makes a strong attack, but will counterattack any weak topspins or loose pushes by his opponent.

Distance from the Table:

The distance from the table for this playing style will vary. When on the defensive or counterattacking, the player will be anywhere from 8 feet or more behind the table. When attacking from his own serve, the player will stay within 3-5 feet of the table unless forced away by a good counterattack from his opponent.

Typical Equipment:

The world class modern defender use inverted rubber on the forehand side, in around a 1.9mm thickness sponge, with speed glue. On the backhand, long pimples with thin sponge are typically used, although short pimples and antispin are seen occasionally. The blade is an offensive blade, although not as fast as those used by the loopers or hitters, since some extra control is needed when chopping. Lower level players use thinner sponge on the forehand (1.0 - 1.5mm) for better control.

If you put a rubber on a steel plate and bounced a ball off it would have to rebound and 0.707 of its impact speed to return even half the energy.  I use the example of the steel plate because it would absorb an insignificant amount of energy.   I question the statement about modern rubbers being that efficient.
 
P,
 
I don't think anyone is vouching for the efficiency of modern rubbers. I think all of us have at some point bounced the ball on a bare blade and discovered that the ball did not bounce up as high as it otherwise would on a rubber (assuming the rubber is bouncy and not tacky of course). Based on this empirical experiment, we conclude that we can hit a faster ball with a rubber than without. Is there something wrong with this conclusion?

No, what sponge has a higher speed after impact than before?  That would mean the sponge magically can generate energy and the coefficient of restitution is greater than 1.


But the thing is, most modern sponges absorbs significantly less energy than rubber top sheets, and the bare wood on the racket face.
So adding more sponge, even though it absorbs some energy,  some how results in more kinetic energy?  Where does this extra energy come from then?
I don't buy it.



Yes it is possible for some sponges to add speed. It's not a matter of adding energy, it happens because less energy is lost than in a bounce against a bare blade.
I see, so keep adding sponge so less and less energy is lost until no energy is lost and we have a perpetual motion machine! Excellent!!!

[quote]
 A good springy sponge will lose a little energy as it dissipates laterally into the sponge, but most of the energy will be returned to the ball as it springs back.
Are you sure?   How do you know?
If you put a rubber on a steel plate and bounced a ball off it would have to rebound and 0.707 of its impact speed to return even half the energy.  I use the example of the steel plate because it would absorb an insignificant amount of energy.   I question the statement about modern rubbers being that efficient.

BTW,  and more on topic.   I find 755 1mm very inconsistent.  I think the sponge lets the pips bend this way or that depending on a lot of things that aren't apparent to the casual user.   755 0X seems to work just fine.

Yes, 755 1mm will allow one to do a pretty good approximation of a loop but it doesn't have the kick after the bounce like T05 does.

Yes, is it possible to really loop a ball with 0X pips IF you have some help from a chopper.   The 0X rubber can't add that much spin itself but the pips can add top spin to the incoming back spin on the ball and the result is a real loop but it is an assisted loop.   I see this happen when I am 'looping' back chopped balls with my hard bat.  The first couple of my returns simply add to the spin until the 3rd or 4th seems to have a whole lot of back spin coming in and top spin going back.

No, what sponge has a higher speed after impact than before?  That would mean the sponge magically can generate energy and the coefficient of restitution is greater than 1.


But the thing is, most modern sponges absorbs significantly less energy than rubber top sheets, and the bare wood on the racket face.
So adding more sponge, even though it absorbs some energy,  some how results in more kinetic energy?  Where does this extra energy come from then?
I don't buy it.



Yes it is possible for some sponges to add speed. It's not a matter of adding energy, it happens because less energy is lost than in a bounce against a bare blade. In a blade bounce, you lose energy through vibration of the blade and the ball, and some is lost in extra deformation of the ball. A good springy sponge will lose a little energy as it dissipates laterally into the sponge, but most of the energy will be returned to the ball as it springs back.

Edit: I didn't even notice that guy above me said almost the same thing, so yeah... what he said Tongue

P,

They're saying less energy is lost during impact against modern sponges than against a bare blade. The result is relatively more speed with a sponge than without. They're not saying the sponge is adding energy to the impact, but that more of the impact energy is translated into ball speed and less to heat and inelastic deformation.
