Pokerstars and Full Tilt there should be no problem, if you already have submitted the important personal id documents.
my experience is, that full tilt is minimal faster on cash outs, but only minimal.
About Dafa, 888, Winner and Pkr i can't help you, i even haven't tried it there to cash out.
But don't forget, if you cash out on Pokerstars there are reports of some players that tell, the you get for some weeks/months an no-runner-account there, that means you will get suckout after suckout, but those are tales, you have to try it yourself
hope i could help you
