I'll play devil's advocate by saying, take a step out of the micro limits every now and then and see how your game holds up, even if it's *risky*.
I think there's nothing wrong with taking a shot at the bigger limit every now and then, especially if it looks profitable. If you're comfortable, and can play your A-game, go for it.
this is for experienced players only, you need to know what you're getting yourself into.
