The new NTN telemark binding system from Rottefella gives you the ability to adjust binding flex by selecting different Power Tubes. The power tubes affect the stiffness of the binding vertically and laterally. For example, a pair of stiff power tubes will be more difficult to flex and more rigid side-to-side.

White is the softest (recommended for conservative, low-speed skiers)
Green is soft (recommended for moderate skiers, variety of speeds)
Blue is medium (recommended for all-mountain skiers, medium to high speeds)
Red is stiff (recommended for aggressive skiers, high speeds)

Bottom Line: The new tele norm.

The NTNs are a completely different animal than your old duckbill setup. On a 75mm binding and boot, the bellows flex contributes to the overall stiffness of the setup. NTNs are designed to rely more on the springs in the binding to control the stiffness of the system. So, the setting of your power tubes makes a much bigger difference than the spring setting on a 75mm setup would.

NTNs also require a shift in technique. In order to properly maneuver the ski, you have to really focus on driving the knee down and bending at the ball of the foot or you'll end up skiing on your tip-toes.

Try backing the power tubes off to the lightest setting and taking them out on an easy slope while focusing on keeping the ball of your rear foot down in the turns. Then, gradually ramp up the power tubes until you feel like you're getting the best balance of control and resistance.

Once you get it all nailed, I think you'll be an NTN convert.
