hi pals, i'm new here, but not new for tennis, i'm 23 and has been playing tennis for 12 years now. i'm also a huge TennisWarehouse costumer but never visited the forum. since the beginning i always used Yonex raquets mostly from 95sq to 100sq. right now i'm using the RDS003. my question is, i never used overgrips cuz i find then to be to fat for my 3/8 grip but lately my hands are becoming to sweat and the OEM grip sometimes are slippery making hard to control my services. should i use an overgrip to make it less slippery? what should i do if i dont want my grip to become too fat? thanks, and sorry for my poor English.
