In reply to featuresforfeet:
Lots of good options nowadays, though it’s often advised not to get a fairly new to market binding, let it have a few seasons to iron out issues.
I have a pretty close match to you for usage, ski level, and build (ok, I am 5kg heavier.) I’ve got a bit of a varied quiver of skis and bindings, and have used a few additional bindings. My go to, and probably strongest recommendation would probably be the G3 ion: a good, strong tech binding, one of the strongest toe springs there is. It doesn’t have the rotational movement or longitudinal play that some of the newer options do, though how much real world benefit this gives is uncertain. It’s very easy to get into compared with some other tech options.
My other bindings are probably less suitable for you: the shift is great for slack country and shorter tours, but it’s heavy. I also have Kreutzspitze GTs on a light pair of skis for longer tours and ski mountaineering, but there is a trade off in how hard you can ski them.
I’m sure more informed opinions will follow mine.
