Thanks again for the replies. A little of my pool playing history might help. I started playing at about age 13, and about 18 started running the local pool hall, so I played every day for about 3 years. Never had real lessons, although the guy that owned the place would throw out advice on occasion. I have put in a lot of hours, playing regularly until I got married, then picked the game back up about 5 years ago after a 25 year layoff. I believe I have improved slightly from when I quit, thanks mainly to learning a lot about how to aim from this site, but I might be fooling myself. I play pretty much every day, but there are times when I wonder if an LD shaft would improve my game, or a different tip, or something I haven't thought about. Thanks again.
