The balls we currently play with now have been with the table at our club house for the past 18 years, so I'm not sure what they are. The HOA was going to sell the table because nobody used it until we started a group that plays weekly.
I understand what you are saying about lessons on fundamentals, although I'm skeptical of who to look into in our area for lessons. Also I am 79 and wondering if they would be worth it at this late date. I do read pool books, watch a lot of training videos, have purchased many of Tor Lowry's videos and practice a lot. We currently play together, about six of us, and are all about the same level and have loads of fun just playing.
Thanks for the advice though, I appreciate it.
