Xplore vs. 3pin+cables

Judging from Tom'd video I'd say there is a big difference activity between the standard and stiff flexors.

Add in that the 11 and 4lb measurements were the minimum amount of force to lift the heel. If you cranked your heel up higher I think the pressure would increase dramatically more with the stiff flexor.

You might be right… this is where Hooke’s Law (mentioned by someone else in another thread) is useless (according to the stuff I’ve read, Hooke’s Law doesn’t apply to rubber).

Direct measurement is the only way to know.

I think you could test the tip pressure using just one scale. In your living room with one ski on, standing on your other foot, try putting pressure on the scale with your ski tip. I'm sure you will get higher weights with more active bindings.

Exactly. And the tip pressure is going to be equal to the weight it takes to lift the heel!

But then you’d be losing several “control” aspects in the experiment. The biggest control issue is exactly duplicating the weight shift of the skier.

Like, I know we’re all “good” but I can’t guarantee that I can *exactly* match leg angles and weight shift two times in a row. I don’t think you can realistically do so either. Not because we aren’t competent skiers in our own right, but because we’re subject to the same human tolerances… and those are always in a state of flux.

You might see where I’m going with all this…

I don’t understand the resistance you guys have. As long as Tom is willing to do it, the experiment won’t cost you anything.

Sounds right to me, and I'm no rocket surgeon.

I don't think you'd lose any control in the experiment. What a skier does with that extra pressure is up to them. One generalization about active bindings and stiff boots is that they will let you do the same thing as softer set up with less body movement.

Regardless, my request for @Tom M stands…

Don't forget, Tom doesn't work here.
