Tripod + PistolGrip Head, and those 14's or 12's? You're off to the races!
Do you already have your system setup re: kill-kit? Meat bags, how they're to be placed in/on your particular pack? You've practiced loading and unloading an object of similar size into the intended way on your pack a number of times, so you can feel very familiar with doing this process in the middle of the night under headlamp? For that matter, trekking poles? Do you already have them squared away for you? Think about maybe a small ultralight tarp that you can lay down to process the deer upon, if you're lucky enough for it not to be on the side of a steep hill. That can be helpful in terms of keeping debris out of the meat there on the spot.
If you're NOT going replaceable blade scalpel... have you practiced touching-up the blade on your fixed or folder that you plan to use?
Sometimes you get a more mature deer whose hide you notice is significantly tougher/thicker, which, if the person processing doesn't know to try to cut from inside, outward after first making enough of initial incision, they could end up dulling their blade even faster yet. So knowing/feeling confident that you know how to touch-up your blade in the field.
Oh!... and if you're going to be making ambush sits in cold places? BootShields/BootCovers!! Game-Changer!
