+ one for FF bags. I own several custom and retail versions. Have used them/FF specifically for years now. If I need another down bag it will be a FFs.
Jackets?
FF makes sub par down jackets by any comparison I am aware of. Certainly by my direct comparisons to other climbing specific for insulation/weight and price point. FF does use very good down, high quality materials and good fill weights. Just really dated jacket designs that are not very efficent by comparison to what is currently and easily available in the market place now. FF's actual weights in my comparisons were way off compared to the published weights. Notably so.
Durability? If you are ripping up down jackets just stuffing them....ah, ya...
good luck on that 6000m down jacket!
May be a synthetic likehe Duelly would be better for your own use?
Some really nice currently available jackets suitable for 6000m. None of them will ward off a sharp axe, crampons or inattention how ever.

Not everyone gets to look at lots of expensive and differing jackets. Since late '09 I made an effort to do so. Two tutorials from my perspective...both surprised me by the time i was done. Some like Patagonia'ss DAS has changed remarkedly for the better since '09. Patagonia as well as Arcteryx have since added down insulation to their climbing specific garments. Others haven't changed at all. And some jackets IMO are not as good as they were previously. There is more at CT on down and synthetic climbing specific jackets if you dig around a bit. Just type your interest into the search function top left.
