As for skinning without touring lock, I think this varies for different people, perhaps base on year/model of binding, weight and style of skier, etc. Your point about the different click positions is a good one. I’ve found that indeed works on some Dynafit bindings, but it doesn’t seem to work on all of them, so I’ve never felt comfortable talking about it as if it was a real feature of the binding. It’s certainly on the list I’ll hand over to Fritz and Dynafit before I leave, as it seems like a very easy feature to build into the binding (a variable touring lock).

I tried once to add a bicycle “quick-release” to a Ramer Classic, to replace the front cross-bolt. The folded lever was going to “hide” inside the concave tuning-fork arm.
