Fintwrote a review of Rossignol Justice Amptek Snowboard - Women's on October 31, 2013
Familiarity: I've put it through the wringer
Pretty flexible, but not choppy at high speeds. Bought this board for my AK trip last year. Despite my first time in deep Pow, and riding a 149, it schralped quite well. Also performed well in the tight woods and bulletproof snow found in the ADKs. Overall, a great board for the buck.
BTW - There is no Magne Traction, and it is not a true twin. It is setback.
