I have an x-jet top on a shortened sn bottom. Really fun ski. Not a barrel like the original bottom deck.
And listen to the ones that have done it. I bought a good deal sold off my stuff for the hull. 7 years later I'm riding it and was stuck a year with no ski then a turd with a stock 650 and pipe. I don't regret it now, but man was it a long hard expensive road.
