Does anyone here play full limit cash games? (I'm in the US)

This has become a passion of mine and i've been trying to play exclusively FLH cash. I have had good success with this pre-BF on Full Tilt; however, I have been struggling for the past couple of months. I've been playing on Carbon exclusively since that's where all my money is at right now. The games are difficult to find at times and I run into a bunch of regs. I've also noticed that once you get above .10/.20 the games are even more scarce.

Has anyone found success on a different network with FLH?

I also loved to play cash games of Stud and Razz; however, no sites have enough traffic to play these games. Once in a while you can find a half full table, but that's rare.
