Meh, if someone wants a high end, softer flexing binding, regardless of age, ability, or wealth, who cares?
Obviously higher end stuff tends to be stiffer and more geared towards an advanced rider, people will spend money on a high end binding, regardless. Smart move on Burton's part, and a valid explanation by the rep. Not something I would ever say to a customer, but I get it from a sales point of view.
I have a buddy who's been on them for all of last year, and I talked to him at Boreal opening day, and he loves them. Really good rider, so I'll take his word on them. If you want to spend an arm and a leg on a softer flexing binding? Go for it, I know people in Vail, Aspen, Northstar, Whistler visiting with some money in their pockets will be. I hear it's a solid binding nonetheless, and I want to put some days on them this year. Waiting for them to pop up on the batcave.
