What do you find works best in a hennessy hammock, the double bubble radiant pad or plain ole walmart pad. Planning on 32 degree bag (more like 40) and reactor lining with long johns. This should keep me good to about 25 degrees. Of course I plan to "try it out" before hitting the trail. I will also be sleeping with thick wool socks and thick gloves. Will a hot water bottle last most of the night? Never hammocked before and plan on using it on a NOBO appx April 1. Getting ready to order my hammock soon. There insulation kit is out of my price range.
