Grand theory

For years the only stuff sack I have used are the ones for my tents, which strap onto the outside of my pack. Now I find myself looking for the stuff bag for my huge WM Super kodiak sleeping bag. Ordinarily I just shove it into the huge pack, but I really do need to stuff it cause even a 6500 inch pack gets sorta over stuffed with that big of a bag.

My own opinion - if you need stuff sacks to keep your gear sorted, you have way too much gear. I guess I also have a zippered net pouch in the top compartment of my pack, for my first aid stuff. But then I have way too much first aid stuff.

A pack IS a stuff sack, why carry extras?
