For what it's worth as I've never hunted BC (I have been on a few goat hunts though), but an 8 lb. Hille for a solo shelter on an early Aug. hunt seems extremely heavy and overkill to me. JMHO. There are a few other things to consider with your hunt. How many days in the field, and what are you going to be responsible for carrying both into and out of the field? Are you taking your own spotting scope, or any other large personal items? The wt. difference between the two packs that you're considering is pretty nominal, but the size difference is not. I had both, but sold the 5900 bag because I have several SG bags that I prefer, and I also prefer a load cell. Given that the Terminus does not have a load cell, you will probably need the extra carrying capacity, especially if you're successful. Unfortunately I still haven't had a successful hunt with the Terminus, so I can't comment on packing a full camp plus an animal into it. Given the size of the tent you're taking, I would recommend the Terminus pack.
