Update (13nov11): Finally managed to get this revision out on snow. See the very end for the results..
First, I would like to thank Jay (tainted meat) and Andrew (Andrew L) and Mike (MD2020) for donating NTN parts for this experiment. It saved me from destroying my own working bindings as the prototypes were made and remodified as problems developed and were dealt with along the way… Thanks guys!
Theory: The theory I have is that NTN has significant resistance in tour mode that can be “detensioned” and improve tour mode greatly.
Analysis: The throw lever extends the plastic tensioning parts to engage the power tubes. Modifying those parts to have less extension could, in theory, leave the boot captured by the claw, but not under tension.
In Practice: You place the modified tensioner in the new de-tensioned mode position. You put your skins on your skis and climb in the modified free pivot mode. When you reach the top of your climb and remove your skins, you also reposition the mid part tensioner in the normal position and your binding is back to normal power tube tensioning for the ski down.
Keep making backcountry turns
