I bought my NTN set up in 2010, back when they were still bright orange and I love them. They're a great binding and made learning tele super easy. Unlike your average tele binding, these have ski brakes too so you can lock your skis togther. I use them to tour as well and the weight honestly doesn't bother me. I feel they are just as heavy as Marker's or Salomon's AT set up. One disappointment in these bindings, though, is that just last week I cracked the metal siding and blew out the cartridges. Now I'm an 18 year old girl, 115 lbs. You would think that metal would be able to withstand my skiing and blue cartridges would be beefy enough to handle me but I guess not... If it weren't for that, they would have a 5 star review hands down. Either way, these bindings are super stable
Oh another draw back is that on super wet days, they do have the potential to ice up under your boot but if you just stick a piece of rubber in there, it fixes it no problem.
UPDATE: So that tiny crack in the orange siding has now spread through the binding. I contacted Scarpa and even though they were out of warranty, they said I could send the bindings in and they could have a look. Well 7 weeks later and many phone calls and emails later, Scarpa finally got back to me saying they couldn't do anything since they were out of warranty. So now I'm stuck with broken bindings, and 7 weeks of frustration, anxiety, and a wasted season pass.
