Hi Dave, my name is Tom. I've been playing pool for 50 years. I played the first 30 years without ever applying side-spin. Bob Byrne gave me the confidence and knowledge to finally try it. After much trial and error, it became easier. Next, I viewed and analyzed over 3,000 shots made by the pros and found that the majority (close to 80%) of tip contact happens at five of the nine contact points on a cue-ball. If the cue-ball was a clock, these five points would be 12- Center-6, 7and 5. You can see this on my website: icueclinic.com. Love your articles and would cherish some feedback.
Thanks for your time,
Tom Van Eck
