For a comparison of Denali Evo Ascents vs. Lightning Ascents read my post #8 under

Since that post I had the
crampon rivet pull out on the Lightnings again (4th time). I sent them to MSR and the guy in the warranty department suggested that they were not going to just keep replacing them. I said they were "defective in material and workmanship" under their warranty, and the fact they kept breaking was not my fault since it was "normal use".
He had the gall to suggest it was time
for me to consider buying another type of snowshoe!!! With further negotiation they offered to
sell me a new pair of Lightning Ascents for "near wholesale" $159.00. I said that was nice, but if he looked at them he would see my snowshoes were in nearly new condition (they spent most of their lifetime broken). All they needed was a crampon which would not break under normal use. He agreed to replace my older 2 strap binding with the new 3 strap binding on the 2007 models. I haven't got them back yet, but if these bindings fail at the crampon rivet, the Lightnings are going into the recycling bin, with the other trash.
I would not buy them again, that's for sure, even though they perform great under a variety of conditions. My thinking is that MSR sacrificed strength of material for weight, for marketing purposes, so they could claim "lightest in their class". All they need is to use thicker gauge metal (or stronger) in the crampon and change to iron rivets from aluminum. I told him all this but he was just a "customer service representative" and unfortunately such feedback rarely makes it back to the design department. And MSR will wonder why there are so many dissatisfied customers!
Update on the Denali evo's I bought last fall: They are much stronger and have been trouble free for the last three months. Same guy, same weight, same mountains, same variety of conditions--and no failures.
