Unless I'm mistaken, Shane named the ski the pontoon. It should stay that way. I'm sure he was in the process of coming up with some crazy new idea for some new improvement to powder skis... and if that ever comes to fruition of course it should be named after him. But why rename something after him if he named it in the first place?
Anyway the way to remember shane isn't a ski with his name attached, it's to ski pow. A lot of us were influenced by him in how we do that. That influence is going to be passed on to the next generation of skiers who are inspired by watching this generation, and the ones after that. That's how you pay tribute to the guy... keep his legacy alive. Keep skiing.
