You have plenty of bankroll for either the 22s or the 33s, provided you are indeed a winning player. (If you're not, of course, no bankroll will be big enough.)

Move up one level at a time -- you'll know pretty quickly if you're comfortable enough at the 22s to consider moving up again. And if you skip a level and start with a big downswing (or worse, find that you're in over your head), you'll have gone through a much larger amount of your bankroll in the process.
