Jay, your equivalent ratings between 3C and 14.1 are right on I think. I used to play 3C a lot, have a lot of tapes/DVDs/books at home, reached a point where I was pretty decent (.6 - .7) and finally did manage to run 10, but was more happy with my consistency. Certainly teaches you a lot about controlling the balls, and improves your kicking/banking/safety play in pool. Unfortunately no tables here in Jacksonville, so I'm not able to play anymore - I miss it...
My high run in straight pool is 72, but I don't play often at all. I think, just maybe, if I concentrated on the game for a couple months I could get back to that point again and maybe, maybe have a chance to run 100. I think the third part of the trifecta is having a hundred break in snooker - for me, that's just unreachable, I ran 49 points once and was elated...
I think it was Don Feeney back in Chicago that I heard has accomplished all 3 feats. If so, I think he's in a select group...
