Great binders!! Matched them with a Capita Black Snowboard of Death for a week in Breckenridge. The combo was very light, and the binders were stiff as promised for hard charging all mountain riding. A comfortable ankle strap is complimented by a toe strap that actually stays where you put it. On hill adjustments were a snap. And a good buckle\ratchet design got me hooked in and out quick and easy.
All in all, the FLUX SF45 is a great 2 strap binding that that has both the stiffness and comfort I was looking for. Well done.
