There's the lifetime stats for me at the Full Tilt HU cash games. HU game selection is probably more important than 6max tables, but I just sit at random tables and if there is some player that I believe is better than me (or at least just as hyper aggressive as me and will create problems down the line), I'll stand up and not play him. Most of the time though, I think I have an advantage over some random player.
Another thing that I do is refuse to play against some person that buys in for less than 40 BBs.Although the random person that buys in for that amount is in general a much weaker opponent than someone that buys in for the maximum allowed, I probably have to device some other style to play that opponent, and I don't really want too drastic of styles when I am playing 3-4 tables of HU.
