Seems like an obvious answer from the pix, but let's just ask it anyway -- you can strap/unstrap like a traditional binding, right?
Also, less obvious -- is the highback sprung in any way? Does it pop open on its own when you release, or does it pop up on its own? Or does it just stay wherever you leave it?
I know you think you thought you knew what you thought I said,
but I'm not sure you understood what you thought I meant.
