I want to try something different regarding my spare ball, and that's to try a different span and pitch on my spare ball to see if it can roll straighter with my normal release. I have till summer to see if this will work for me - I am not bowling leagues this season, I'm baby bonding. I do get some 2 to 3 hours of practice time before closing at least once every two weeks.

I've gone through 3 spare balls with cracked out thumb holes in the last 5 years because of my EOE roll which is my release on spares. If I throw my normal release at spares, my spare ball has a tendency to hook on really dry lanes. That is why I want to try this "experiment" while I'm off form leagues.

If I remember..... I think CB uses a different span/pitch for his spare ball, but I'm not sure. Have any of you ever tried this? or are doing this? Input appreciated.

(My thumb pitch is 1/8 away (lat) and 1/8 forward; span is 4 1/2 cut on both.)
