You have to be honest with yourself and say are you making good shots. Is the ball reading the lanes correctly. Just because you're striking doesn't mean you're making good shots. Are you striking with each ball you own? Are you flattening your wrist to make your hooking ball go straight? Can you make your spare ball hook the lanes? Pick off only the ten pin on first ball, take out the 6 and 9 with next ball. Do the same on the left side of the rack.
