What else can I say other than it's the best snowshoe I've ever used. Before I dropped the cash on a pair of my own, I did a number of hikes in rental shoes from local shops in the North East. I tried Tubb's, MSR Evo's, and a few other random pairs. Once I went on a winter overnight with a borrowed pair of the Lighting's I was sold. They weren't the lightest pair, but as far was performance per ounce, nothing can touch them. They feel firm, but allow flex without worry. The ascent bar comes up without any effort. The multitude of gripping features is great for ice, snow, and rock combo's. They pack up nicely too, and go on any size boot with minimal effort. Also everything is easily replaceable on the binding, so if something breaks, it's an easy fix. These are by far (in my opinion) the best snowshoe for alpine ascents. They also work very well with mountaineering boots. No fit issues and in my opinion, they work best with a stiff synthetic or plastic boot, rather than a hiking/backpacking boot. They really are a great snowshoe.
One thing to note about the MSR EVO, although lighter and cheaper there is a tremedus amount of flaping from them. I thought about getting the EVO to save weight, but when I tried they I felt like I was all over the place. When you lift your leg to walk, the binding opens fully, but because they are so light, they bounce on the pivot point. This gets really annoying after a few miles and sprays snow everywhere. Just wanted to mention it before you let either weight or $$$ steer you away from the lightnings.
