I was looking at the resi pro grip but wondered if it would be a bit too thin?
I have to say, I wasn't keen on this frame with the leather grip it just felt so much better with the weight right at the buttcap rather then distributed up the handle.
I've not noticed any lack of stability with lead just at the top of the hoop. 12g at 3 & 9 must feel super solid, do you lose much spin with that setup?
It is definitely a thinner grip. I'm playing the other 2 with leather and wilson pro OG, and to be honest when I'm playing real tennis and focusing on a match, I don't notice the 1/2 size difference. I should mention all of the 3 I've customized with TK82S pallets and Head pro buttcaps w. trap door, which changes the feel of the grip a bit.
With 6g at noon the frame still has decent stability, but I figured the 12g split would absolutely feel like a brick from the baseline, and it does. Regarding spin generation, I've always been a believer that spin is 99% technique, so I don't really think like that when I'm trying a new setup. My thought process is just "how does this setup feel on shot X or shot Y."
I'm surprised you guys are getting the sw up into the 335 range with just 5-7g in the hoop. I have mine (16m) set up with 5g in the hoop and overwrap for a total weight of 341g. When I had it tested on RDC the sw was 316 strung.
When I got my first 2 16M's, I measured the unstrung SW, and they came in at 277 and 281 Unstrung - with gut/poly they ended up 307 and 312 so almost exactly 30 pts added by strings. It was fairly easy to get them up to 330+ by adding 6g right under the bumper, plus overgrip, dampener, etc etc... I have 6 of these frames and I've never experienced one with the 301 strung SW that TW reports. I think they must have measured an under-spec one for the website, since mine come in 8-10g heavier as well than the listed 328g.
