Jim,
As far as balls go, I do bounce around a little bit, depending what I am doing. However I have done mapping with the different balls and know what % of distance variation I will get.
For important CC and WGT tournaments I use a Nike L61. For other tournaments I usually use a Cally L33. And I often use a WGT G13-SV (in pink) for practice rounds. If the WGT had just a little bit more distance I would use it most of the time. The first time I played the new Best of Par 4 F9 with that ball I was 6 under, and should have made at least 1 more bird.
As far as the Nike and Callys go, I already play my RSI2 PW with very little spin, as they will back up big time with that club. Nike VR PW is a little bit less due to less spin built in the club.
Some of my problems are do to being a dinosaur. Time and gravity do take their toll on the body. I take that into account.
