I've grown to trust the PLUM 170 like no other binding. Simple in function. Made like a tank. Lightweight. I've skied it all over the world and never had a failure or issue.
The bindings were good for the reason that I purchased them. They are extremely lightweight and efficient, and are quick and easy to transition from climb to ski. They also have a good feel for how they ski relative to the style of bindings, so for most of what I do (climb up then ski) they are perfect).
However, what I do find is that the rotation between flat and rise (and eventually I figured out I will likely need the 180 deg rotation for the high rise) are extremely difficult to maneuver. I was basically using all my might and popping blood vessels to get it to rotate. Definitely not possible to do with skis on which makes flat to climb and flat to ski transitions very time consuming. It is very possible that this is user error and I need to adjust something but overall I found this quite a nuisance (especially as all of my past bindings modes change with just the flick of a pole).
