Like most folks, I have too many packs. For mountain hunts, a MR PIntler, my son will wear to meat haul, and a SG Evo for myself. I like MR, have known Dana for 40 years, but gotta say that his packs often seem just a hair overbuilt for what ever I end up doing. The Evo works very well as a compromise, the MR seems just on the big side for the compromise approach, but carries weight great - it might get the nod for an extended spike setup, or solo, though. We use load cells on the pack and bag setups, to carry camp/gear in, and hopefully meat out.
Now that I've assembled a crew of younger guys, we hope to hunt as a foursome in two pairs. We would congregate and all 4 haul meat, at least to a first stage away from the carcass, cooling and in a spot permitting an observable approach -- it's bear country.
I may actually be putting the Evo on another guy, and rig some extension straps for my SG Avail, a brilliant day pack with a flap extension pocket on the pack. My reasoning is the compact form factor of the Avail offsets the 'first load' hassle of dense weight far behind me on the outside of the pack, which won't be bad at all if can get this mod worked out. It's just a super tidy run and gun setup, I really like it for any situation I've encountered so far.
We have a meat cart in the pickup if we get lucky close, and/or can grab a meat pack at camp or the truck after the first load. My limited experience so far is that with several guys, as the old guy I can easily end up with a big first load of weapons, excess warm clothing and gear, which the Avail can handle.
Getting rid of all the baggage lets the meat loading process start with a clean slate on those packs, so to speak, and one guy can easily allocate one trip to all the crap. The heavy load haulers have a more compact and manageable payload, and I can route find and mark, clear obstacles, stage and assist at rest stops, etc.
If I am alone or one of a pair, the Evo will get the nod. I bought the Evo bag very reasonably from a member here, then bought the Evo Minimalist frame and load cell setup from the company. If I only had one pack, or was buying a first pack for whatever situation, it would be the Evo. Good luck and Happy Trails -
