Yeah, that's the pad. I use the 3/4 length. Just sort of shingled under the inflatable so that there is more coverage on the sides. It works for me, but I am a person who sleeps warm and has a 1/4 inch of body fat everywhere to help out. I use a bag rated for 45 degrees, but also have a set of clothing for sleeping that is warm.
Reason I take two pads is to have a backup closed cell pad in case of a leak in my inflatable.
My best advice for hammocking is to be super flexible, sometimes its best to just put the pads on a picnic bench, or spread a tarp on the ground. I bring a hammock to stealth camp mostly.
There are hammock forums that you can read for lots of tips, some guys are obsessive, I dunno, I never read those, just did it till I figured out how it worked for me.
