Waste,
Here is the problem with Gil getting a SJ. First, he will have to gut it, defoam it and reinforce it to make it even strong enough for FS. He allready has everything else he needs for FS on his SXR, except a light enough hull, right now. From the list of parts he has, he is allready faster than most 701 Superjets. If he goes aftermarket with the hull, he is now light as a SJ and strong enough for the abuse. It is probably actually less work to switch out the Kawi hulls than get a SJ.... Remember those Aftermarket SXR type hulls are made for freestyle. I just think he would lose his A$$$$ on all the $ he dumped into the SXR allready. I ride superjets all the time, and do not want to switch at all. The lightweight tossability of a SJ just isn't worth the poor handling to me.
The only way it would be worth it for him to go blue at THIS point is if he buys a reinforced ready to Freestyle SJ. Then he would be in the same place as an aftermarket hulled SXR.
