I've been tempted to get a Hennessy for years and insulation has always been a concern as I tend to sleep on the cold side. Which model quilt do you use? Also, do you use a pad? I have a Big Agnus inflatable insulated pad (mummy) I would consider using that even if I didn't inflate it. I would definately use it inflated if I would have to set up on the ground using my trekking poles (turns the hammock int a bivvy of sorts).
