Would anyone drop down?

ROI is around 8% at the 33's over 1300 games.

I would move up.

8% at the 33s equals 12% at the 22s. So if you think you can do better than 12% at the 22s, go ahead and move down. Don't be discouraged by 8% though. It's solid.

What's your aim? Making some of money? What's your ROI in the $22s? If it's > 12%, then you might want to consider it. However, it takes a lot more than 1300 games to get your ROI accurate to within a couple of percent.

I'd keep playing, work out where I can improve, and win.
