Correct. If you look at the sir floatalot you can see it has a very small effective edge, it would handle like a very short board IMO, the nose and tail only come into play when you hit the powder. Im not sure it would be great for the groomers but I may be wrong! As I said I would love to try it, it is an exciting shape.
The neversummer- meh. Heavy, not exactly a great shape for powder IMO. Riding my Neversummer SL in Hokkaido was like having an anchor tied to my feet. I only ride mine when the snow is shit.
