More whip is the usual answer. I settled with 3/8, use to play 5/8 or 1/2, but I think mine is actually 1/2 with overgrip since I changed my replacement with a Babolat syntec Pro. Pros, CAN but not always depends on person to produce more racket head speed, cons, more wristy, may not suit your stroke. I went to 1/4 and felt my one handed backhand suffered. Really preference. Gotta try for yourself.
