I play at both. NLHE Sng's on Full Tilt Poker
and limit razz on stars. I found myself too frustrated on stars, without trying to cry cheating or that nonsense, with some of the beats I kept getting. Just the way it kept going.
Only thing about Stars is that for the low stakes ring games, especially limit games, getting FPP's is impossible as, for example, on the limit razz tables lowest limit, the rake doesnt go above 40c, but at least Stars has limits that I am suited to for these games, FTP doesn't.
