rakeback vs bonus?

[TWINUNO]

I kno absolute you keep your rakeback as well as bonus but for a lower limt player playing 1/2 is it better to just chase the bonus's out there instead of getting a rakeback deal and losing some of the bonus's? I kno BW offers a monthly reloads through hollywood but there is also rake back, would it prob be better to play wit the bonus?
I know rakeback is free money but at what levels do you think this is essential, since your in it more for a profit then clearing bonus's. Right now all i do is clear bonus's.
