FYI; cable bindings, such as Rivas, are flexible enough not to require a release mechanism. With proper adjustment, you'll blow out of the binding if it all goes wrong. Others, such as Voiles, have release options. I use the same ski crampons as AT folks. As for the rest; well, that's all personal preference, fitness, and skill.
My bindings do release, thankfully.
I was a little concerned about it, but I think I got over that fear when I started snowboarding (the fear of having equipment stuck to me while going ass over teakettle down the hill).
