i figured this shit out along time ago building skateboards/longboards and riding troublemakers (only other big h-lam twintip):
ply construction is almost entirely dependent on the glue that is used for the laminate for strength. im not sure whether Abangs use wood glue or epoxy in their core construction (im gonna take a guess and say wood glue, cause epoxy aint cheap, and theres alot needed for h-lams, but correct me if im wrong), but wood glue breaks down /stretches incredibly fast under the kind of flexing loads expierienced while skiing, and "pop" of the laminate is lost very quickly, especially while buttering where the ski is held in a flexed position. skateboards get away with it because the concave creates a beam structure that is signifigantly stiffer than the flat profile of the laminate. epoxy is MUCH better at maintaining its form and strength in these kind of laminates, which is why a GOOD hardwood Vlam will hold camber almost indefinitely, because the fiberglass/epoxy is locking it in that position, and the large blocks of solid wood deform much less than the glue/veneer layers. skis that decamber are built too fast with too humid of wood, and therfore the actual wood layer is aloud to deform, and the ski stretches out of shape.
that being said, Abangs are dirt dirt cheap to make, and once the hype dies down on them, im sure youll see them selling for less than 200 new, easy, and the 100 dollar mark is by no means out of question. and if line can sell a decent park ski for that much new, than thats a damn good way to get kids into the sport, and props to them for that, even if they dont last more than a season or 2.
