I just put on my Tx Pro boot and put it in the M2.1. Without being buckled in, it twisted out easily without the duck butt engaged. Buckled up, also came out easily by twisting both on my foot and just by hand with the heel down and all the way up. Dialed down the release to minimum and stepped in with the duckbutt engaged. I was able to twist out without having to use an impulse, just twisting, but it was harder, for sure. When I was young and skied alpine, I used a DIN of 7 on my toe and was able to twist out. This seemed close, but not as much of a clean release. Once the duckbutt releases and the pins release, there's some residual resistance to rotation.
Well, it sounds like it works….. can it twist out with both the toe and the duck but connected, when your heel is way up off the ski? Much harder from that position?
Once the heel is up, I can see two major planes of rotation. The plane of rotation that would activate the release is in the plane that really just places the ski on edge. I doubt there would be enough resistance to compress the release spring in that case, but little danger of injury.
The other plane of rotation would be dangerous for the knee - in the extreme - and it would be 90 degrees out from the plane of the release vector. Imagine the heel up, and then rotate the lower leg (the lever from ankle to knee) either left, or right, parallel to the surface of the slope. That could put huge loads on the knee with no real hope of a release unless you break the plastic holding the duckbutt, I think. That's the difficulty in designing a rotational release in multiple axes.
I'm also in the "throw myself over the handlebars to fall" camp.
Interesting. Should x post to BCT thread. Jasonq did his tests with a torque wrench… so some direct measurement, values posted. Maybe some pressure on the pins at work… based on the hinge point… maybe not. Worth posing the Q to him anyway.
I don’t really want to join another forum. But, reread that thread.
Looks like jasaonq was torque testing the binding with different toe pieces and with/without the duckbutt engaged. Excessively high DIN…for the standard 3.0. But the discussions about forward or downward pressure on the toe piece creating higher release values was speculation based on geometry. Looking at my toe piece doesn’t look too likely. There is the fact that the hinges on the toe piece are very slightly outboard of the pins so maybe. But, the cone shape of the pin and hole seems like would tend to open up the claws no matter which direction force is applied.

I appreciate all the thought that people have put into this, and the encouragement for recovery.
I’m not looking to place responsibility outside myself, gain attention or sympathy, etc, etc…
If there is any value in all this, maybe it causes people to look a little deeper, do some research, consider variables, resist false hope, be more cognizant of the risks and anything one thinks he can do to mitigate or minimize them.
@Manney, Just now.
Cleared for full weight bearing on that foot now (IN WALKING BOOT, the visit summary says).
(That’s cleared for — not necessarily ready for!)
Oh, man, here I am posting pictures of my foot again!
