I play 25nl and will soon be moving up to 50nl, play 500 hands/hour and I play at Pokerstars.

I am looking at my "rakeback" at P-stars, and think it is definitely not what I could be getting if I switched to FT. Am I right to think that even at the 25NL that you can get 27% rakeback at FT?

I only ask b/c right now I am pretty sure I am only getting about 8-10% equivalent through P-stars through their "cash bonus program"
(I am a Silverstar)

Over my last ~30,000 hands I have paid about $600 in rake, and accumulated 3162 VPP's (4743 FPP's), which is about equivalent to $50 in rakeback.

If I am right then at FT my rakeback would have amounted to $162.

Am I missing something? Are there any huge drawbacks to switching to FT? I know that they deduct their points or whatever from your account but that is essentially what P-stars does too...
