A short update on this: I've now played close to 5000 hands at 10NL and I'm currently running at +8ptbb/100, but there are still a few hands I don't like the way I played.
I also played a few sessions at 25NL. The first ones were really bad but the last ones were definitely better.
In terms of poker sites
, I'm now mostly playing 10NL on pokerstars as well as 1 table open on bodog. I hate the software there but it's literally like shooting fish in a barrel. :-) The 25NL I play on full tilt.
