Help please. Have a 15.1lb Rampage, have been using for 3 months, have had finger pain and strain in shoulder to back muscles. Had the shop change the finger pitch and re-drill the thumb for easier release. Low-Med rev,15-16mph avg. speed. The finger pain from knuckle to tip is terrible, especially the ring finger. My friend rolls the TI @ 14.2lb and he loves it. I have had shoulder injury in the past but the most recent problems developed after I got the Rampage. Is it a drilling issue, weight issue, ect...?? I am considering the 14lb TI to see if I can get rid of the pain and try another ball but still want the hit. I bowl 10-20 games a week 6mo a year and every other week the other 6mo. Hope all this info helps as I need relief.

Sound very painful I always have a back problem and Hardly stand but once I have my 15 pounds ball I instantly cured. You got to love the game! Try it

Had the ball checked today by another proshop and he could see nothing out of wack. He did say my ring finger is short and that my span looks ok but obviously still having pain. Is lower wieght the solution?

Fingers are 0 degree pitch, we have openened the inserts up, shaped them a little. Do u have a pic of the inserts you referred to? Do yoo sell them as well?
