Quickest game to clear bonuses

[Trikkur]

I'm normally a 100NL at FTP for a pretty good winrate, but recently I decided to do some whoring. I just deposited into Cake Poker, but since I only had 500 I'm stuck playing 50NL and the bonus is clearing really slow. Is there another game I should be playing? I heard limit hold em clears bonuses quickly, but I'm pretty clueless on that game. Should I learn the game to clear bonuses when they pop up? I've heard the winrate at limit holdem is much lower than NL so is it worth the decrease in winrate to unlock bonus? Any help on these subjects is appreciated.
