I have a WM Megalite B/C I wanted a bit more room in a summer bag. Plus it has no side baffle and one can move the down from top to bottom a little bit. (Not easy with that high lofting down.)

I think WM has outstanding quality an you'll be very happy with it. You'll especially like the full length zipper on hot nights or when you unzip, hook the foot over the end of your mattress and use it as a quilt.
