Where to play high stakes NLH?

[dthf90210]

I want to play high stakes $10-20 NLH (and above) 6-max cash games. Full Tilt has a lot of these games but I am already a member and thus can't get rakeback there. Where do people recommend I play for these types of games? UB doesn't have a good selection of these games. I would like to be able to play these games with rakeback.
