I am still learning insulation types and such, and thinking of purchasing a 3/4 UQ. Specifically the 140oz 3/4 flameThrower UQ. The dimensions are 40" X 54". If I am laying asymmetrically do I have enough UQ to cover me at a diagonal lay? I remember some math buffs on the forums....so correct me if I am wrong please. I did the Pythagorean theorem on these numbers and got a diagonal length of 67.2". I am 5'6" = 66". Seems like I got enough room yea? I plan on using a black rock pillow too, so I could even subtract my head length knowing the pillow will take care of that. Anyone successfully cover themselves with a 3/4 UQ or am I overlooking something?? Thanks!
