well, my mind is in full swing of creating a 3 season down quilt set, so I have put a lot of thought into making it now. I am leaning towards building a snugfit look alike, and here are some thoughts I have had on the design.
JRB makes their quilts rectangular, and brings the sides up around the hammock edge. the snugfit is shaped like a hammock to cradle the hammock. I think the speer design is harder to make, but more efficient.
but since the hammock is a HH clone, i will be sleeping on 1 diagonal mostly, so it only needs to be shaped that 1 direction. Instead of being parallel to the hammock, although you are not, would it make more sence to have the quilt be on an angle? it will be difficult, but I would say nicer, so you have no "wasted" insulation.
als, JRB makes their quilts "flat", so they can be reversed if you so choose. the snugfit is created in its special way, where it contours the shape of the hammock. but the 2 sides of the quilt are not equal, the bottom is wider, so it wraps around. Once again, this is harder to make, but seems more efficient.
jacks, I really love your products, and they have inspired me greatly. it is just I like to design, and the simple rectangle doesn't cut it for me. this is not a personal vendetta against your product. so no hard feelings, right?
