I ride a K1200LTC and hammock camp with it..... FWIW, since you noted the value of reduced bulk, a good point, under quilts are normally a much lower bulk approach to bottom insulation than pads..... But it will be pricier.... watch the resale posts or seek a rare irregular.
But, hey, I'm biased.
PM me if you want to persue a detailed discussion of MCs and hammocks.
