I'll delete this if you dont want others to see it, but play the 2/4 6 max games at Stars. Once you learn and can master 6 max (just do 2 bb/100 over 10k hands at each level) then you'll be more than qualified for playing higher limits. 6 max has got to be the number one thing that kept me from really improving my game and I wish I had learned it well before I actually did.
