Holy crap! 60 pounds?!!! Geeeeesh!!!!! That's enormous. I can't even imagine needing that much junk. Wow!!!
I limit my guys to a maximum of 35 pounds, or else we don't fly. The Pipers that I use have a flyable payload of 300 pounds, after 3 hours of fuel and pilot. So, if a client weighs 200 pounds and camp/food/salt weighs 80 pounds, then a client needs to keep his total gear weight to less than 40 pounds or we don't fly. But, that's the way I do it.
Some outfitters fly BIG aircraft into pre-established campsites and in those instances, a guy could possibly (probably) bring more junk. I mean, if a guy just has to have the entire house including the kitchen sink, there are outfitters who cater to that sort of thing.
In any event, have a great hunt.

Haha safe to say you're a little emphatic on being spartan. Didn't say I was bringing 60, but I'm allowed that amount which includes everything (rifle, pack, whatever). Can't imagine I hit close to it as I don't need to bring food/water/tent. Yes, flying a bigger (likely) float plane into base camp then horseback to spike camps. This goes to my point earlier that the OP should discuss the weight requirements of the outfitter and decide his allocation. Should he be going on a "kitchen sink" hunt then he should have plenty of room for spotter haha.
