Hey frock,
I think Charlest is correct on the ball burning up. Your description of 7-10's and hitting like a "wet noodle" definitely sound like it's not retaining enough energy at the pins. Couple of suggestions, 1) apply a coat of Clean and Sheen to it by hand or 2)go over the ball with a gray scotchbrite to smoothen out that 600 grit that's currently on the surface. Either action should put a smoother surface on the ball and help you clear the heads easier while retaining the proper amount of energy for the backend. Hope this helps...
