I always hated no having pins to throw at. You could say it looks like a good shot, but with no pins
there, you don't know for sure if it would have been light, heavy, or flush. With 10 mins of
practice in our 5 man league, I get plenty of practice. I can throw up to 10 strike balls plus all
the spares if I don't strike. If you can't get loose or lined up with 10 strike balls, maybe you need to
run some laps before bowling.
