best empire bonus?

Is the best bonus for empire right now still the default BW listed one (20% up to $100)? How are the 25NL and 50NL tables there? I've been working on Absolute but the software is driving me up a wall and the low limit 2+2 infestation is ruining the play (<25% vpip tables anyone?).

Also a party question - I have an account there but I never deposited in it - am I still eligible for sign up bonuses or do I need to wait for a reload?
