I've played on a lot of the sites pre and post Black Friday and would be happy to answer questions. I tried in the other thread and did answer a lot. I also think there were similar threads in other forums on 2p2 that are useful. I will agree that there is a lot of confusion in those threads though
The only one I haven't played on recently is Cake Network because they do not allow KY or WA residents.
Merge definitely has some good skins and seems to be the #1 choice of US players ATM. I personally had moved a lot of my play to Merge before Black Friday because of Full Tilts horrible support. The skin I chose was RPM for a few reasons. They have a sub-forum here on 2p2 at the top of the Internet Poker forum. Their support is the best in the business IMO. RPMSeth is extremely quick to reply to PM's on 2p2 or emails sent to him and RPMJon is always very helpful in Live Chat. If you check out their bonus's in the Sub-Forum you will see that they have some great bonus's. They also offer the standard 35% RB and also a 6.5% VIP Points system.
I've not played on skins like Lock Poker, but I've heard very good things about them and I believe they are widely considered to be top-notch.
The software on Merge is the best available to US residents post Black Friday IMO.
If you have questions on specific rooms or skins I'll try to help and I'm sure others will too. I know there is a lot of questions about where to play. I've also played at True Poker, Bodog, etc....
