It amazes me. Most freestyle riders own short (sub-158cm) boards, usually rockered that are slow, soft and lack pop. The incredible thing is that nearly all of the riders that hit huge jumps ride larger, cambered boards because without them they simply cannot generate the speed or spin required to be competitive, let alone knowing how to carve.
A quick note on "street" snowboarding (bungee based, handrail or roof-drop, redirect driven riding): while I think it is dangerous, borderline irresponsible to encourage riders to emulate this type of riding (I have two mangled fingers that I can use as evidence of its dangers) I do admire the "do it yourself / anti establishment" spirit of it all. Skiers are now copying this type of riding, but snowboarders invented it (well, skateboarders, but still...). This type of riding removes the need for a lift ticket and cuts the resorts out entirely, making an otherwise ludicrously expensive, for-the-privileged sport accessible to those of very modest means. There are literally sponsored riders who have very rarely been to a resort, who will switch smith-grind a double kink like no tomorrow, or boost off a roof top and crank out a 900. I think this is very punk-rock, for lack of a better phrase. Just as punks made loud, innovative music by removing the need for music lessons that many of them could not afford, snowboarding is innovating by removing the need for access to mountains, expensive training camps, condos near resorts, and all the other "lucky sperm club" benefits of being affluent. This is particularly true of hardboot based racing: if your parents cannot enroll you in a program, buy you competitive equipment, get you in gates several times a week, etc... you likely will never be competitive on a national / international level, baring extraordinary talent, of course. A $2000 Kessler is simply out of the realm of affordability to most parents, let alone their kids. For adults, probably still true.
I would not recommend street based riding to anyone, however: frozen concrete makes the hardest snow seem like powder. I think it is important to recognize that snowboarding continues to be an innovative presence in the alpine scene, even if the innovation is the removal of the alpine scene. Skiing cannot say the same in this regard.
Still, obviously, I think carve based riding offers more to the long term success of snowboarding.
