I can't help with the MTT question, but as far as microstakes 6max cash 'reg infestation', Black Chip is much worse than Carbon imo. Bovada is the softest as you would expect. I really like Carbon, better software and more fun than Black Chip, and I like the different table themes. I believe America's Cardroom is another skin for Black Chip. They're both on the Winning Poker Network. So it should be just like Black Chip.

As for getting enough MTT action you'll probably have to play on more than one site to get enough games, I imagine. Maybe we'll get lucky and PokerStars will let us back. They paid the DOJ a half billion fine on behalf of FullTilt when they took over so they should be in the government's good graces. Let us back, PokerStars! pleeeeeeeeeeeease
