14.1
I only play 14.1 and one-pocket these days. I should say I 'practice' only these two games, I don't 'play' against anyone much these days. There are NO 14.1 players in the deep south (never have been), however, there are plenty of one-pocket players (very good ones!) In fact, I see Marshall Carpenter (Tuscaloosa Squirrel) most days of the week at my local pool hall, still shooting a great game.
If I lived up north, especially NY, I'd probably only shoot 14.1 by choice. Throughout my time in college in the 80's the preferred game was 9-ball and I got sick of it for a lifetime. I'll play 10-ball now, but I despise 9-ball.
