I love the I-poker sites (Titan, CD Poker and recently downloaded
Noble).
Titan is my favorite of course. Tons of freerolls, some decent MMTs and of course the BBP league. Plus I'm looking forward to playing in the $100 Million Dollar freeroll (ok only really half mil pot and the rest is a jackpot but still). Though I qualifed through CD Poker for that one. And one day I'm going to hit that damn Maui jackpot (or consolation at least the consolation prize) if my internet connection can hold for 5 straight tournies.
After that I got to go with Absolute. I'll dabble with Prima sites and have started playing a little at
Full Tilt.
