I'd like to hear some thoughts on this as well. My concern with the Moment is the interior space. Looks like the dimensions will hold my prolite 4 nicely but thinking my sleeping bag (marmot helium long) will be prone to touching the sides, thus condensation issues. It's a pretty recent release though so been tough to find good reviews online

Now I'm leaning toward the Double Rainbow for the space which appears palatial for solo.
