winner at 20/40, loser at 30/60?

[Lestat]

80k hands is still very much the short term online especially when multi-tabling. I suspect you've ran well at 20-40, are running poorly at 30-60, and are also having some adjustment problems in the tougher 30 game. It is most certainly some combination of all three.

If bankroll isn't an issue, I'd suggest not giving up on the 30. Yes, the 20 games play looser and more passive, but if you really can beat the 20 for over 1/100 while 5-tabling, there's no reason you can't beat the 30 (although for slightly less per 100).
