Most fall bear require skinning twice in a way. Removing hide with as little fat attached as possible will help keep it from experiencing hair loss. And then skinning the fat away from the meat. I find the fat holds more heat in than does leaving the bones in. Though I do encourage you to do both. You will be happy you did by the time you get to the truck with that last load too

I usually carry four Alaskan small quarter game bags and one full size deer bag for the hide. Once you get the fat off that is more than enough.
Any small para cord is good enough to hang small quarter bags. One of my favorites is 160# braided Dacron fishing line. The Muzzy bowfishing line is good too and comes in florescent colors!
Since I am not normally in grizzly country I never worry about hanging them high. So it is very easy. Biggest thing is to avoid direct sunlight and to get good ventilation. Try hanging the game bags by a cord on both ends making a long horizontal meat tube rather than a big bowling ball in bag. This allows more ventilation and reduces trapped heat.
In August I say "Pack All Night" if you have to. If in a hole or other unwise trekking in the dark spot I like to leap frog quarters to a trail or safe night travel route during the day light hours. That way I can utilize a safe area during night time to get the meat out. No meat is worth getting injured in the back country, but with a little pre planning you should be able to take advantage of the cool darkness without worry.
Biggest advantage to me is to play all scenarios over in my head before I find myself needing to come up with a plan while the adrenalin is affecting my thought process. The worst case scenarios in my head are almost always much worse than the actual reality. I think that is a good thing and helps us prepare and organize the pack without a bunch of unnecessary weight and bulk. Yet allowing a prepared plan for just about every surprise, good or bad!
