The leather grips seem to have compressed a bit, while Gamma Dermagrip really worked for me( thin and tacky ). So I have the perfect grip size on the most used racquets, the ones that I still didn't use have a tad larger grip, due to leather still not compressed .
I have just received 4 Babolat Skin Feel, I'll try them on my AG100s while TW doesn't stock up the leather grips. If I like it better, then I order other 4 SFs for my 4D300Tours, otherwise I keep with the leather grip. I just need to check if my hand will get 100% used to all the new callouses
