I used to be well into it. Made 6 centuries between the ages of 18-20 (highest break 132) and was on the B team for pool for Rileys for a bit. Those centuries were all made in solo practice on the line-up routine.
Don't play much anymore as I don't have as much disposable income now that I'm running a car, not nearly as talented as I was a few years ago! Still enjoy the game now when I do play, in fact maybe more so now since I don't get pissed off when I'm playing badly.
