Which of these has the softest NL100

Hey guys!

Gonna open a new account with rakereduction, so i will get rakeback everyday. But i dont know which room to chose. I need a room with many players and tables as i often multitable 9-12. But i also want a fairly soft site!

Absolute poker
Ultimate bet
FTP
Cake poker
Poker heaven
Sun poker
Pacific poker

ty guys

AP, UB, and FTP are your only choices (i think) for playing that many tables. well, not playing, but having that many good tables available.
