Pretty sure there used to be CC games at Carbon, but the cash outs would take months, and even some I think had to wait a year. They also made it so you couldn't even play freerolls unless you had earned 1 of their Carbon Points, or whatever they're called. They used to be pretty decent, but I stopped playing their a few years back and just play at ACR now. Sure, I wish I could play somewhere else, but the choices are limited in the USA without waiting 6+ months for a cash out. Maybe Carbon improved their cash out times, but they lost a lot of customers and their reputation went with it a few years back IMO.
I am currently winning on the Winning Poker Network.. I was breaking even, but started actually reviewing my sessions and trying to plugs my leaks and have been doing pretty well, all things considered.
