I went through years and years of trying to get shops to re-fit me and the would all just kinda look at how I threw the ball and say my fit was fine. I knew my fit felt like crap for years. Finally I took it upon myself to get my fit straightened out and used the wiki fit on Bowlingchat and made some slight changes and couldn't be happier. Everyone makes comments about how short my span is but I love it and couldn't go back to being stretched out if I wanted to. I pick up one of my old balls and can't believe I was ever even able to throw it like that....Not surprised my middle finger started hurting before I changed spans....BTW I shortened it about 1/2". Sad that so many pro shops thought it was fine that I was so stretched.
