The MX package is definately the way to go. Glaser sails has a very good guide for rig tuning and sail adjustment. It's a fast and forgiving boat. I didn't realize how resistant it was to pitchpoling until I sold it and bought a Blade. I never used a spin on it but there's a lot of spaghetti on it with the barber hauler, 4-way jib lead adjustment etc... The newer style rudders are much better.
