hi guys i'm quiet new here. i have a question to ask

right now i'm a mainly 1-2 limit player playing on ultimate bet with 28% rakeback. i play a lot around 15-20k hands per month so i actulaly get like $300 in rakeback every month. recently i have found that UB is pretty tight and hard to get paid off when you have a hand. i play by the guidelines of SSHE. i'm wondering if i should move my bankroll, about $750 to party poker and just play straight up poker there and perhaps multi table. do you guys think that's a good idea?

basically it comes down to
either

UB + 28% RB or PP straight up

thanks in advance
