However, the $200 in neteller is a differant thing. I would like to turn this into a substantial bankroll.
I highly recommend you play limit for a while to rebuild your bankroll while finetuning your game.A $600 to $280 swing is pretty hefty,and I'm not sure if NL(or even PL) is the game you want to play while you're trying to rebuild.I recommend you take that $200 and play the microlimits at PokerStars(or any other site that offers limits under the Party Skins .50/1 tables.When you get that to about $500 you can hit up a Party skin then.

I started off playing NL as well;in hindsight now I realize I was both underbankrolled for the limits and inexperienced;my PT stats remind me of that everyday(it's a humbling experience to look at every time I update my logs).However I think grinding it out at the microlimits will prove both educational and less stressful for you to rebuild,and will give you time and room to grow.
