In my experience, If you place the opening of the Kifaru bag "up", it minimizes blood leaking out in the pack. I normally strap it to the outside of compressed pack via cargo chair, so its really no issue. I'm very happy with mine.
Wow man you pack all the meat the furthest away from your body you can get. For me the closer to my back with the heavy meat bags the better. But if the works for ya or just going a short distance without camp to carry on your back also could work. Just thought it was interesting.
