These are my observations so far: 

-G1 seems to be easier to control in the short game on both sides.

-G1 is easier to block with albeit, especially with a slightly more open bat angle.

-G1 is amazing for flat hitting early from the bounce. So long as I go forward it feels like the rubber just wants to put the ball on the table.

-Opponents top spin is much easier to control with G1.

-Lifting backspin with a brushing stroke also work well. 

-Only mid- to far-distance looping and 'proper' aggressive opening shots are better with T05.

In short, at the moment (after having played with G1 for about 8 sessions) it feels like G1 is a very big improvement for me.

One worry is, of course, durability. I did notice that the rubbers were clearly factory boosted because of the domed shape, something that I didn't use to see with new Tenergy. Is there a significant drop off in performance with G1 after a couple of months once the booster wears off? And is the rubber suited to just being reboosted every 2 or 3 months?

I like it more than T05 as T05 requires much more skill - I think that on my level and slightly above (and of course lower) G1 for FH (and C1 for BH comparatively to T05FX) suits more.

I do not reboost it - just if drastically reduces grip - clean and set bit of Johnson baby oil for 20 minutes - after that remove it and clean it again.

Of course just IMHO

Yeah - put that to the topsheet, not to the sponge.

Sponge in G1 is much more durable and it's less thick than in t05 so lives pretty longer than it's topsheet (just my own note) 

Oil on the topsheet surface for 20 minutes makes it grippier even though topsheet is really thick in G1 and it is really grippy because of mechanics of pretty long pips under it.

If you apply oil for more than 20 minutes  - it can ruin the surface and if much more time (like couple of hours), then even can lead to bubbles.

Thank you for the reply :) 

Yeah, I do agree that it basically just seems to be a rubber that is suited to a lower skill level than T05.

Interesting what you said about the baby oil. I did buy some Falco Life Extender to try out, will use that before I go down the baby oil route.

Have you used Fastarc P1?

Profile of the rubbers ... all went up?

Do you mean that the playing public (EJ's?) noticed that certain ESN rubbers "bite" the ABS balls more than other topsheet formulations?

They might lack power a few steps off the tables, so may not work for the highest level, and they don't really work well with boosters. 

I used Tenergy 05H and then Dignics 09C. It is funny.  I couldn't use Butterfly rubbers because I found them too bouncy but when I tried those ones, I found them usable.   I also noticed some extra spin for how I play, but whether it justifies the price... I don't change rubbers often so I guess it doesn't really matter. 

Its like 2 hours training with personal coach. What gives you more benefits? I am so much biased against that dic*nicks rubber ... Can't stop bashing it every time I see :)

To be quite fair, it depends on the coach.

It is atrocious though, especially when you consider how many rubbers one goes through over a 5 year period, and likely wanting 2 sheets at a time.

I think the Vietnamese have it right by frankensteining different unused cuttings of a sheet in order to make say 1.2 or 1.3 sheets of rubber per sheet purchased!

Tbh it's probably the best rubber on the market now, and butterfly is pricing it accordingly.... The only equivalent is a boosted H3 blue sponge national which is also around the same price range 

I never liked the bounciness of Tenergy. Dignics 09c is a semi tacky rubber which makes it super different to all other Dignics rubbers... If you drop a ball onto the rubber the bounce will die off in 3 bounces or so. So this means it's also super controllable in serve receive with huge spin in opening loops especially if you use proper technique powered by body rotation.
