So.. While JoeCedar is talking up the demise of his Lighting Ascents, I thought I'd revisit my Northern Lites that I have. This is the third winter season, I'm using these and can report that I've basically had to replace the three rivets in the binding with bolts and nylok nuts due to the large aluminum washer failure. The big AL washer that the rivet goes through has a tendency to basically bend into a concave like manner which eventually fails and then the rivet simply pulls through the binding decking.
So far, my fixes have held up, and I carry a spare bolt/nut/washer setup and tools to fix. It is almost impossible to fix a broken rivet in the field because usually the old rivet is still intact, but without the washer, the crampon has no chance of staying close to the binding. Once, two of the three rivets fail, the binding usually fails because the snowshoe will just rotate/pivot around the one remaining rivet.
My decking is holding up, one rivet in the back is starting to enlarge and I can see some signs of stress on the back, probably because I tend to jump down ledges on occasion.
The kevlar(????) mesh underneath the rubber binding is starting to show from age, might want to try to protect that some more soon... Over the years, the protective rubber cover is starting to wear.
Overall, happy with them, they are fairly durable, despite their insane lightness...
And customer service has been good. I paid for a crampon that I broke (out of warantee) and the guy there sent me three crampons so now I have spares.
