Monica H.wrote a review of Dynafit FT Mustagh ATA Superlight Speedskin on December 4, 2010
I was very disappointed with this skin. I could have gotten 2 sets here in Canada for what I paid. I thought I should buy the best and spend the money. They do have noticeably more glide but it comes with a price. I did not get the grip on the up that my old pair gave me. Even my ski buddy noticed I couldn't climb quite like I did before. I am grateful that backcountry is taking them back.
If it is all about the weight and glide these skins are for you. If you want good grip to climb steeper slopes stay away. Also the little plastic nub which attaches the skins to the toe of your skis sticks straight up. This makes it really easy for it to be kicked off by the other ski.
