I am actually a rep for DB and can probably answer any questions that anyone has. The first pair have just started shipping out and the performance has ben described as 'supernatural'. I can also get you 5% off by entering referral code 1321 in the order form. Email me email@example.com if you want to know more. I can also arrange demos in Summit County Colorado this winter. They are incredibly light, and durable. Snowboard width edges and kevlar in the bases. I can send you a file with the specific if you ask.
