So far I've racked up 6000 hands at $25NL full ring. During that time I haven't even thought about the 6 max tables.

Can someone give me some advice about when it is appropriate to give 6max a go? Obviously it involves playing hands with some not so premium cards, playing well out of the blinds and having good judgement regarding when you are ahead or beat.

When did you make the transition? Did you stay at the same limit? How did it all go?
