For me the answer was yes, but only for for/rev. My lateral pitches stayed the same. It just boils down to comfort. I have enough flexibility in my fingers to use 3/16 - 1/4 forward. However, when bowling two handed, my fingers at times wont come out cleanly. So I had to go to dead zero. I have neither forward nor reverse. My suggestion is before drilling anything new or plugging anything, get on the lanes and bowl two handed with one of your current pieces. If it feels fine and the track is not rolling over the fingers, then dont change a thing. If something feels off and/or you are rolling over the finger holes, then definitely go to your pro shop guy and make any necessary changes. As an FYI. My laterals are 3/8 in both fingers and I use Vise Power Ovals.
