am i ready to go from 8 tabling 50nl to 8 tabling 100nl?

Hello fellow 2+2ers.

So here's the deal. I've had about 15k hands at 50nl, averaging 7 tables. i'm at 9.23PTBB/100 after these 15k hands. My account is at 2k.

If all I care about is making money and building my bankroll (safely), is it time for me to move up to 7-8 tables of 100nl? Can I just keep playing the same game I have been playing, ABCing it? What else should I take into consideration before making the leap?

Thanks for the replies
