Party PL Omaha bankroll question.

[Lafortezza]

I'm sure it's been asked before but I'm asking it again!

My current br is $700 on PP. I've been 3-tabling the $25 PL Omaha tables for the last while and have steadily made money.

When should I move up limits to the $50 and then the $100 buy-in tables? I won't be cashing out any time soon.

Just wondering how many times the buy-in people are playing with before moving up limits.
