Just ordered this ball a couple days ago. Doing a 12 lb experiment. As a 59 yr old one hand no thumb bowler, I have trouble getting enough speed on the ball. Currently using 14 and 15. Just got a 12 lb spare ball (white dot). I can throw it a couple miles an hour faster between 16 and 16.5 on the monitor. It will be interesting to see how this ball will go through the pins or if it will deflect too much. I should be between 400 and 450 revs.
