I've used the "2p heatsheet" alone and easily stayed toasty warm in these temps. Condensation has nothing to do with it as long as you "do not" deploy your bug netting at night. This is because the netting captures the moisture from your breath and soaks everything.
As far as durability goes, I've used a single "Adventure Medical Heatsheet" for years without any damage. They're much tougher than you think, or at least these are.
If you get a little cool simply slide an aluminized windshield heat reflector (the kind with the bubbles) in between the hammock body and the heatsheet.
I posted some information on that one time, you should look at it and the picks.
Now, that being said, I use a -8 degree down bag in cold weather and a 47 degree bag in cool and warm weather.
Here's the link to my thread and you can view the 2 pics showing the heatsheet in my gallery:
One more thing, I use a Clarks hammock so I can't say how well this will work on yours.
