1) play the level that you're most comfortable with, and play well

2) find the best supplemental income opportunity that level provides, whether it be bonuses and/or rakeback. there is no one solution that will fit every kind of player.

3) move up when you can accurately calculate that you can make more money overall (actual play + bonus + rakeback) by doing so over whatever you're doing now.

simple, in that order.
