[pct-l] Ultralight Down Coats: FF or WM?

[Deems]

I've researched this down coat question for over a year, and it would be 
nice to hear from some of the field testers that took the step and bought 
either the Feathered Friends Hyperion Epic coat (11oz) or the Western 
Mountaineering Flight coat (10oz). The WMF coat shell seems a might fragile 
to me, and it would be my dog's warm bed each night.  This coat would be 
used for summer Sierra and PCT type hike scenarios..I lean towards the FF 
since I have a FF Hummingbird bag,  but I would like to hear from the crowd 
about their experiences with either coat, pros and cons.
