I've played almost all the different variations on games that Full Tilt offers, and I always go back to the plain old ring (cash) games and the 6-9 player SnGs. The other games are sometimes more exciting, but I make, by far, the most money on the basic games. Poker is, after all, a fairly boring activity. I certainly mean no offense to anyone here, but if you're playing for excitement then your playing for the wrong game. That's what Black Jack is for. More than 60% of hands in Hold Em aren't playable right off the bat, so most of the time a good player will just be sitting there twiddling his thumbs, so to speak.
And, like Chris said above, the people at the $5 and $10 tables practically give their money away to you if you play solid aggressive poker. There is SOOOO much money to be made at those tables if that's where your bankroll puts you.
