What site do you play on? I play NL 50 and NL 100 at Party Poker, and while the NL 50 game is surpisingly a bit tighter it is a quite easy beatable game. I dont know about other sites, but at NL 50 at Party the players seem to have TREMENDOUS respect for an early raise. On many other sites I just raise in as usual but at Party it can sometimes be a good idea to limp re-raise your strongest holdings from early position. Yes, this sort of gives ur hand away but at least you extract some value from it. 2$-raise is sort of standard at NL50 and I wouldn't consider going below that.
