I just got a chance to take some pictures of the finished quilt.
Shell is Momentum 90, insulation is 18 ounces of 900 fill which gives about 5 inches of loft. The footbox is sewn and I installed a drawstring in the shoulder. I don't have a very acurate scale or I would post official weight but I would guess about 23-24 ounces.
ETA- The blue cloth on the sofa is an under quilt in the works
