I have the roll to play any stakes I want. I consider myself a world-class tournament player. I do not however consider myself a world class cash game player(yet). I think in most games above 10/20 NL I do not have an edge. I know I have an edge at 600NL and I also play 5-10 and 10-20 NL when one of my mega-fish "buddies" are sitting. I can make more 6 tabling 6 max 600 $/hr than 10 tabling $109 SNG's so 600NL is currently my primary game.
