Thanks Lanche, no rush, whenever you get around to it. I read a post from someone a few years ago that used someone's mid (IIRC it was MLD's) and said that two packrafts tucked in there nice. I don't have a packraft buddy yet so I was thinking solo. This shelter has me intrigued:

At ten ounces, that is light enough for solo use, and I think a packraft would fit under it no problem. The silnylon version at 18oz is half the money
