need moving up advice: $25NL ----> $50NL

[The_Bankroll]

I've finally got a roll where I can take shots at $50NL, and can hopefully move up permanetly soon. I play on stars, and one thing I've noticed is there is definetly a lot more aggression at $50NL than at $25NL. I get played back at more when stealing blinds, get floated more, raised on later streets more, etc. and I've had some difficulty adjusting. what would you advise for playing in games like these? I've been a small winner @ $50NL for the short while I played it (about 10k hands) but I want to get my winrate up above 2PTBB/100. I read the link in the uNL sticky, but I didn't think it was much help here, as the games have changed quite a bit over the last 6-12 months.
