Worth switching sites for rakeback/datamining?

[metrognome7]

I'm marginally successful at 5NL and now 10NL HE playing on 'Stars. Would it be worth it to transfer some (or all) of my relatively meager bankroll to FullTilt or some other site so that I can take advantage of datamining and arrange for Rakeback, both of which are prevented on 'Stars?

Thanks.
