ok..my mom has had a columbian 300 wicked
she had it drilled to the max cause she dont put alot of revs on it and throws it average of 13-14 mph
usually starts at 15 board throws out to 5 board and it swings back in to hit pocket
welp one week in thursday night league she shot 579
the next week 420....ball wouldnt move
same release it looked like but ball wouldnt come back at all...I cleaned the ball with some black magic ball cleaner..(smells like windex ..lol)
but it still didnt do anything...can someone please help my mom out to what to do wit it?...
ty
KEEP ON BOWLING BABY!!!!
