These are probably the best back country binding I've used. They are fairly light while still providing good support. I have these mounted on a pair of G3 Tonic and rock them round the Italian Alps for 7 days and they were terrific. Two others also had these binding and they all help up great. Probably one of the best parts is that because the way the binding bends, you're able to use the crampons while the heal risers are flipped up. Great for those steep icy hills. I haven't had the problems with the heal flipping downs, but I believe it's all in who installs the heal risers and if they do it right. Mine were just fine but another member in my group risers would filp down occasionally.All in all this is a great binding all around binding.
