Replying to new bindings

afternoon folks
im in the market for some new bindings and of course it is a choice between rossi and look. right now im on some rossi power 100's from last year, but since im getting new skis i figured what the hell ill get new bindings and keep my old skis and bindings together. anywho, what are the main differences between the p10 and p12? why buy one over the other? i also need to make sure i get a freestyle/freeride binding and not a race binding like i did previously. any input is greatly appreciate
