I'm just a smidge shorter at 6'1" 220, 33 inch waist. Kifaru cavern, medium belt and I think large straps. I have fairly broad shoulders. With a guide lid I can do 6 days easy in archery solo, could probably go longer. Had enough room for most of my camp, plus 60 pounds of meat. Best piece of gear I've owned in a long time.6'3, 225 here, looking for a comfortable, weight carrying pack as well.
Just got the 44 mag too. Wife can use it when I'm not.
The comfort level at 90+ pounds was unbelievable.
