I seriously wouldn't use any type of mason's line, the diameter is too small not to a) cut branches, b) cut hands. It's also really stretchy, which is actually sort of a "feature" of the line..
Been using this stuff extensively throughout my life for it's intended purpose, and while it works great for hammock whipping, or even a clothes line, I'd stick to something slippery, low stretch, and sturdy, for bear bagging.
I recently posted trying to find something lighter than my 7/64th amsteel blue for bear bagging, which weighs around 2.5oz for 50ft. After reading the info out there, decided to stick with it.
If I'm hiking for 7 days, I'd rather carry 7 days worth of food, instead of resupplying, so I prefer the performance that the Amsteel offers.
