Just play what you are most comfortable with. Any style can be very profitable as long as you keep working on improving it. Cardsman and I like to rib each other about how we each play the game--he is tight and very agressive while I am very tight and moderately aggressive. He is 20/10 and I am 15/7. My PTBB/100 is slightly higher, so being tighter than the optimal does not mean I am less profitable. Lastly, the other thing you need to be careful about is being caught up in the numbers instead of playing rational poker. In other words, don't start raising and playing all sorts of hands just because you heard 20/10 is da bomb. That's a recipe for disaster if you start playing hands you are not prepared to play properly. I speak from experience there so I've been there and done that. Lost a lot of $ too...

The main thing I would do if I were you is start raising a lot more hands pre-flop. Every time you raise pre-flop on PR, I fold unless I have KK or AA. There is little mystery on what you are holding when you raise pre-flop when you are 11/1.
