moving up stakes

[jvans]

So far over 30k hands at 50nl im winning 3.2BB/100 hands, i want to move up to 100nl but absolutely cannot afford to go broke as poker is my only form of income this summer. i have a bankroll of about 1700. is it possible im just running hot at 50nl? is 30k hands a big enough sample? is my bankroll big enough to move up? I'm used to 12 tabling but i figure i'll probably only 8 table if i move up, at least for a while. all criticisms and suggestions are welcome
