"Honestly for almost $600, a cuban sack would have been a nice touch."
I have a Lightheart solo with cuben upper and silnylon floor, so pretty similar. Mine did come with a cuben sack, and I suggested to Judy that it not do so in future (so maybe this is my fault). A month or so along on the CDT last year and my stuff tent bag was somewhat shredded; I started carrying the stuffed tent inside of a plastic shopping bag to protect it (I carry my tent in a mesh side pocket on my pack).
Cuben is great, but not super durable for use as a carry bag IMO.
It's a great tent, though. You're right about the little elastic loops, and note that for my tent the one place it wasn't seam sealed well was right there; only an issue in hard rain of significant duration. Ditto the zippers, treat them with a bit of care. One of the zipper pulls on mine is wonky now (but there are two pulls per zipper track, so now I just use the other one).
