Ok.
Lets say we cut the soft powderchannel/concave/tunnel in the midle, like on a splitboard. So the tails can flex indipendently. Maybe even cut away the midle 1/2 half, like a narrow swallowtail, with bent up inside edges.
Do you still think it would it make any negative difference in versatility to a regular swallow or fishtail board?
Regarding, press, grind, sanding, and everything else: It works fine on the Volkl Selecta, so why not just scale it up..?
