I only chose Carbon to start out on b/c you can run it on a mac. I think it was very recent that they changed their VIP program, which is total BS.
Also, SNGs are anonymous, so you can't be sure if you are sitting with regs or fish. They are trying to appeal to casual players, so they are making sure most casual players can't se VIP points... ugh.
I know they remove your VIP points after a month or so, I'm not sure this is standard for poker sites
, but these are things to consider if you are thinking of switching from PS. They used to have really cheap Hypers that i played, but since then I've stayed away, so not sure who's playing em nowadays.
