Western Mountaineering vs MSR

wm always meets or exceeds people's expectations of warmth.

Since you want a 20 degree bag/quilt, I'd take care of that first, and get something great. Nunatak, Katabatic, Western Mountaineering will use a good chunk of your budget but are worth it.

the feathered friends or western mountaineering options are top notch.

Western Mountaineering is one company that comes to mind that makes high-end, performance sleeping bags and also includes some more generously cut styles (semi-rectangular) among its offerings.

If I was going to spend that much on a quilt I would get one from a down specialist company like Feathered Friends or Western Mountaineering.

If money is no object and you want a free standing tent, then Big Agnes, Nemo, Sea to Summit, MSR are good options.

If you want better control, more efficiency, better wind performance then look at Soto or MSR.

I often reach for my alps gear more than my expensive MSR gear sometimes.

MSR seems to be keeping the tradition alive and I like that I can see the design style living on, but I miss Moss.
