I never said you can't play tight, and well post flop. However, it is pretty easy to play post flop if you are only playing 10% of your hands preflop.
Congrats on your profit from the small blind.
These are my NL stats from 25NL - 200NL (I don't play much NL, obviously.)
Now it could be that I am just running really well over such a small sample size, but I doubt it.
I also disagree that playing HU will teach you more about ring games than trying to play every hand at lower limits.
