Doz Texas rig G&H deeks, let the sand out of the keel, 1oz weights or even less, $5.99 dove stool at academy, cut the pouch off, hide in cover. This will weight nothing.
I have had a bad back for 20 years. One mile walk-ins I'll take 18 deeks, Mojo, stool, small back pack with coffee and jerk string, shells... But on uneven terrain I would not take this much gear, cut the deeks back to 1 doz.... And, the cabela's jeanwaders makes them long walks much easier..
