Right now I use P-1R 0.5 more often than any other rubbers...

I chatted with WCL on facebook the other day, he'd like me to change back to 1.0mm, but I just find it so vastly different than the 0.5 (aka 0.3~0.5), and I lose the ability to bump well at the table. Why did he say 1.0mm? To keep guys at my level honest who like to dead ball things to the pips and or slow spin loop.

He hasn't coached me in person for a while, and I don't think he knows I twiddle and chop with inverted so much. LOL.


Nice... Also I am sure I don't have to remind you of this... while his recommendation is very valuable we need to always remember that the guy is a former 2700 (?) and can chop with anything. He is Joola sponsored and often chops with Rhyzer max against his students. And Rhyzer is faster than the Tenergy. Btw I am pretty sure he already switched from JSH/P1r to Joola Chen Weixing /Joola Octopus for the same reason.

Exactly. So he changed from Hurricane 3 to Rhyzer? I can't believe he went to a tensor!


He uses tensors to train... Joola posted that he plays matches with Golden Tango PS. Not sure whether this is the case or not.. If I end up in his group at one of the upcoming Opens (hope not :) , I will confirm.

It's amazing what sponsorship deal can do... I also suspect that he's not really competing that much these days, mostly coaching, so actual rating/wins is not that important.

There is a French defender, Eric Adam (The Butcher), who plays for a French second division club La Garde. He uses D Tecs without sponge but with 3 glue sheets to soften the impact of hard shots. There are several videos on YouTube of his club matches. The equipment might be unusual but it certainly works for him. He is a bit of a character anyway & quite entertaining to watch

Steve

INGENIOUS FRAUD.
Illegality of this kind is surely inexcusable for any competitive player.
Butcher's current setup is an absolutely illegal structure, some mockery. The present combination of Dtecs single sheet integrated with a triple glue underneath is obviously over 2 millimeters thick. This ingenious guy of France does not look to have a whit of respect for Table Tennis Laws, nor any decency for his opponents.

2.4.3 A side of the blade used for striking the ball shall be covered with either ordinary pimpled rubber, with pimples outwards having a total thickness including adhesive of not more than 2.0mm, or sandwich rubber, with pimples inwards or outwards, having a total thickness including adhesive of not more than 4.0mm.

D.tecs comes in a 1.6mm sponge... let me tell ya, Iggy, 3 glue sheets are nowhere near that thick!

"Quick glue sheets are 0.05mm thick transparent sheets which have two adhesive sides. "

.05 x 3 = .15mm

A far cry short of the 1.6 sponge, my boy!

I think the rubber with the three glue sheets need to be 2.0mm or less, not 4.0mm because there is no sandwich (i.e. sponge). Of course that doesn't mean it is illegal like our Russian friend is saying: it still might be legal.

GRASS D. TECS bare TOPSHEET GOT BEYOND THE ALLOWANCE OF 2.0 MILLIMETERS. IT IS A MANUFACTURY LAPSE, POOR QUALITY CONTROL. THE RUBBER SUCKS, SORRY.
Yes, Grass D.Tecs sandwich rubber should be a legal product as long as it is integrated with a sponge layer.
However, the Grass D.Tecks bare topsheet without sponge is an outlaw. Its total thickness is now measuring of 2.15 millimetes, far beyond 2.00 millimeters that is now the fixed limit for ordinary topsheet.

The image attached is from the paper Table Tennis Rubber: Tribological Characterization, by Varenberg and Varenberg (2012). The rubbers used in the experiment were provided by two random individuals, and not by Tibhar directly. This dates the rubbers to before 2012, since the study was only published in 2012. It is well known that Tibhar changed the geometry of the OX Dtecs to shorten the pimples - indeed this is mentioned on this very forum in 2012. So sorry, wrong again - unless you have data that post-dates the geometry change, there's no evidence to support the claim that an OX sheet of Dtecs today is in contravention to the thickness of pimple out topsheet rules.

I spoke to him about this, he was just trying the new equipment, hasn't switched permanently.
