I've got 4 Osprey packs. I generally like their fit and features but imo they are too light on padding and suspension for heavy loads.
I have an atmos 50.
That said, my buddy helped me pack out a deer this weekend with his atmos 50 which he bought because he liked mine (for backpacking). I opted to take a bigger beefier Gregory Baltoro, which is where I would steer you for heavier loads.
