That doesn't sound right? What's the grip elasticity? Also, I can't think of any grips as thin as 1mm. I've seen 1.3mm grips and even Wilson feather is 1.4mm. I ended picking one up and opening it. I haven't installed not yet but the grip and layer of foam is pretty thick
Thanks for your thoughts. By the way my level is certainly way below yours (I'm the European equivalent of a 5.5 player but practise with juniors who are semi pro) but I'm getting to a stage where the little things in terms of racket customization etc matter more than before. The funny thing is I'm 45 but play better now than I did 10 years ago. I guess you could say that I started loving and understanding the game much more after my 30s.
Yes I think my stringer was exaggerating when he said the 2.6mm compresses to around 1mm but basically the message he was getting across is that the 2.6mm gel spongy feeling of that grip (Xcel Gel Ultra Comfort) tends to shrink considerably to at least 1.3mm after a few hours of play. From my perspective, the direct consequence of a shrinking grip in play is that all of a sudden balls that had depth, lose that depth and instead there is more spin and angle on my shots but it becomes unnatural to my usual game (my shots are neither flat nor too spinny - somewhere in between).
I'm now trying babolat syntec Pro as a replacement grip which is 1.9mm but should have much less elasticity so the feeling of the grip size should be pretty much consistent across several hours of play. The other option I guess is going down the leather grip route but as I have a history of tennis elbow I prefer to use that as a last resort as it will add considerable weight to the handle.
I have also just ordered the new sky blue Yonex 98 305g in L4. Have been using Technifibre tfight 300 rs in L3 but essentially my stringer customised it so it's more like an L4 (I use Wilson Revolve spin the green version 1.3mm and string at 21.8/22.8 kg with a strip of gamma lead on 3 and 9).
I'm hoping that with the yonex, even if I end up facing the same "grip shrinking feeling issue" that I will not loose depth on my shots by using the same power, despite a shrinking grip.
As you're semi pro I would really value your thoughts on everything I've shared regarding my current racket set up.
