Nevermind, spoke with one of the Jack's today and he put me on the right path. dedicated underquilt will be a better fit. Nuff said.
So I have picked up a used sierra sniveller for a really great price and feel like I would love owning the stealth to compliment it as an under quilt/top quilt combo. This would give me the ability to move the quilts from either position to meet a wider range of temps. I have a Clark NX 250 and a Grand Trunk UL and I am wondering about how to mount either sniveller as an under quilt of both of these hammocks and would a heavier bottom or top quilt be better for lower temps?
