This may be redundent, but have you cleaned it after every session? I know a guy I bowl with had the same problem. Once he started to clean it after every session, the ball came back to life for him.

BOWLING IS FUN NO MATTER WHAT YOU SCORE. BUT A 300 IS ALWAYS NICE.
STRIKE ZONE, ONSLAUGHT & PYRO. STAND 22 AND THROW 10 OUT TO 5 AND CRUSH THE POCKET. AT LEAST THAT IS THE PLAN OF THE NIGHT...
GOOD LUCK AND GOOD BOWLING!!!
