Best of luck. Take whatever is the most "bomb-proof" setup you have, preferably not more than 8# or so, and lighter is better. Rock solid stock bedding and scope mounting are paramount. Depending on your mounting setup, a 2nd scope in rings that's sighted in and ready as a backup isn't a bad plan and in most cases adds less than 2# to your gear list.
On most of my rifles I use a torque driver for re-assembly. Assuming I've done things properly and have stress-free bedding and scope mounting, I can take things apart, torque them back together and maintain zero. When everything fits properly, you should be able to start a group @ your zero range, take it apart, put it back together and continue shooting within the same group.
I don't even like to change slings or flipper lens caps within a week or two of a hunt, but, I do want to know and have an available plug and play solution if something goes sideways.
I'd put Flitz gun and knife wax on everything that sits inside the inletting of the stock, it's an excellent waterproofing product.
