Should I divide my money into two sites, or play the one I'm most...

[ceegee]

Comfortable with? I play Full tilt with a certain familiarity. Their blind structure and game selection etc... I want to get into Ultimate bet because they have a 111% bonus going on and I wanted some change. They have a faster paced more aggressive structure. What do you think? Divide money equally or what? I have 160$ to play with.
