most of these decks are constructed of a birch core and fiberglass layup, not gonna snap any time soon. when using composites you can adjust the flex patterns of the board allowing more energy return, the longtreks was impressive but at Ultra we're talking 200+ miles within 24 hours. longtreks was actuals skated on custom deemonseeds, which are traditional rayne construction, fiberglass and bamboo. the thing with LDPush is that they're not traveling with 30lbs of gear, they're trying to push their bodies to their fullest potential, its like people trying to hold out the longest standup slide. hell, why do Ronins need the support piins? no other trucks use them, but Ronins use support pins because they provide a unique feel and offer a crazy amount of stability. why do DTC wheels have aluminum cores? why can't they have normal cores? the same can be said for these, as its all a matter of perspective.
in skateboarding, its all preference, and for a lot, these work better for LDP than other decks.
debate is love, debate is life.
