Replying to Binding+Ski

I just got a pair of 159 fugatives and I have a pair of public enemy's 169 with Rossi power 100 or somethin like that they match the ski great but are as heavy as the ski itself. both skis are 04/05. I am looking for a good binding that is lightweight for the fugy's or should i switch the rossi's of the PE's and put them on the fugy's and get a light pair for the PE's? I ski the PE's all mountain which is fast and steep stuff and i'm goin to use the fugy's in the park. What bindings should i get and what binding should i put on which ski ?
