If you're playing micro games, play on Stars. The games are tougher - this might sound like a bad thing, but it's not. If you play only at the easy tables, you might win and move up faster but your game won't improve and you won't learn how to play against regs, so you'll struggle as you move up.

No micro stakes table will ever be tough, and if you find it tough then it's a clear indicator that you need to work on your game. If you can't beat the "nits" (aka regs) at micro stakes, you definitely won't be able to at higher stakes where you'll encounter more and more of them. Micros is the best place to learn how to beat them.

There's no point playing micro stakes for the money, partly because of the low stakes and partly because of the rake. You should be using the micros for practice and refining your game.
