In LHE an accepted winrate would be around 3 BB/100 (so multiply this by the number of tables you play). Realize that a $500 dollar bankrolled person would be playing .10/.25 NL making 10BB/100 = $2.5/100 (remember a BB is twice the big blind), where that same bankroll is good for .5/1 (or higher) for a LHE player, making 3 BB/100 = $3/100. If you play LHE it is reasonable to play higher stakes, and the winrates are about the same if you play at your bankroll.

my point is that the winrate in $/100 is about the same in both games. food for thought.

and as a sidenote, I tried limit to clear my party deposit bonus... I got absolutely raped on the BEGINNERS 1/2 LHE (-3.5 BB/100) compared to my NL25 6BB/100 (not so good really but hey its positive and only 6k hands). Could be variance, but I won't be playing LHE for a while.
