My hunts are 4hrs minimum and typically all day minus a quick run to another spot or the truck for a quick hot meal. I cannot and will not sit in a saddle that long not an all day thing for old guys and bad knees. I'm gonna use the XOP Holiday Harness this coming year with my loc-ons. I'll be comfy and able to shoot backdoor as well with that set-up. My Millennium M7 is plenty light enough to run around the mountains if I wanna play the mobile games. Oh, the holiday is cheap too.
