I got Stoxtrader's LHE book for Christmas and it was a shock to see the stats he had on the 6 max LHE pros. Under 0.5 BB/100!!!
That just sounds like a worse variance ride than SNGs.
IMO, LHE is still a tough place to make money online. Live is a different story, but I went up and down in my 6 max limit play at the end of the year and I just shelved the idea of that being my focus.
