Please tell me that your not using the Rossignol bindings that the Sultan package comes with on your Raygun?
Basically, you're going to have a great time on the Raygun, aside from the camber differences, its a higher spec board than the Sultan. I went from a Rossi Decoy traditional camber to a Neversummer SL reverse camber, youll find all the things that Nivek said are correct with the addition of it being just plain all round easier and more fun to ride to ride and less fatigueing through out the day.
Didn't get bindings with the Sultan. I use Flow Flite2s and am either going to move them over or buy Flow NXT AT.
