RB noob seeks RB pro for guidance

[Bobb]

I have 300 on its way to my NT account right now. I am trying to figure out if I should sign up somewhere with a RB deal or try to find some bonuses to clear first.

I'm leaning toward RB. I have found sites that have 30%+ with Ultimate Bet, which seems pretty good to me.

My questions are: If I am playing .50/1 limit, is rakeback worth it or should I be trying to build a roll through bonii/playing and wait to get a RB deal when I am at higher stakes?

I've also heard about some sites (Prima skins) that have 60%+ RB. Should I be trying to find a site/RB deal with the most players and/or fish, or just look for the biggest RB deal I can?

Sorry for this scattered post, any advice or knowledge you'd like to share with me would be GREATLY appreciated.
