A little info in your profile would help a lot. Are you a stroker, tweener, or cranker? High, medium, or slow speed? What kind of lanes do you bowl on and how are they oiled? You said the pin is above your bridge, do you know where the CG is located? Is there a weighthole?
10 pins are caused for a lot of reasons, but the simple explanation is improper entry angle. If the ball is burning energy too early and rolling out, play the oil line longer (move inside, tighter line) or polish the ball some. If the ball is still skidding near the pins, scuff it a little (small steps). Ringing 10's are more subtle. Read Ron C's finger dancing tips.
