“But am considering getting something new to shave some o z's.”

Something to shave oz besides WM? That’s a tall order. WM uses 850+ fill and Montbell uses 800 fill. Plus Montbell uses a 22% heavier shell.

Right on, but if I go from a 20 degree bag to a 30 degree bag I will shave ounces and possibly save money. So my quest might be to try a different brand and to cut costs, while shaving some weight.
