I have now had 3 days on my new NTN binding. Quite different, but opens a whole new area of control. You have adjustable resistance when you flex, meaning that the energy you put into the turn pushes you into the next!
This is the future!
Decided that is was time to upgrade to NTN after about 8 years on telemark. This boot beats the Scarpa T2X in stability and comfort.
