To quote David Downer “…snowshoes are very specific to the conditions.”
My recollection is that the shortest Lightning Ascent are a bit over 4 lbs. (without floater attachment). The Evo Ascents without the floater attachment, a bit under 4 lbs.
For day snow shoe hikes and short 1,2,3 night winter snow camping trips here in the California Sierras, I went with Evo Ascents years ago since they are a $100 cheaper, perhaps a bit more compact, and slightly lighter.
I am walking with the snow shoes strapped to the pack from the CalTrans SnoPark lot to the trailhead and on the first 1/2 mile or so of trail. So the ability to pack the wag bag, the snow shoes, and the snow shovel onto the back of the pack in a compact way was important.
If a strap or other bits breaks, MSR sells all the replacement parts.
If you are of the buy once, cry once, mentality go for the Lightning Ascents. For this season, you might have to accept what is available on the market.
