When you've been at it a while it really comes down to take / not take items, it's all good gear, just different stuff for different trips.
This fall I have a shortish bear hunt and a longish mule deer hunt. Take / not take is probably going to break down to a helinox chair zero glassing chair at 18 oz, and my "good knife" at 10 oz vs a replaceable blade 3 oz knife.
Water sources play a part. Good clear water and I'll take tabs only. Drinking elk wallow water and I want a good filter. If unsure about water sources, i'll take the filter.
I don't eat breakfast when on a backpack hunt. I drink coffee, and then eat dates, almonds, pecans, craisins, epic bars, lara bars, etc. Snack all day and then eat freeze dried for dinner. GU gels for big climbs.
One thing I did take last year was a bag of Oberto bacon jerky. I thought it would be a different flavor of jerky, no big deal. WRONG. When I opened that bag on day 3 or 4 I had intentions of saving some for my buddies....nope, I ate the whole thing right then, then turned the bag inside out and licked out the crumbs. Best thing I've ever eaten.
I'm making my own bacon jerky this year so I can control the salt and preservatives. I'll take a LOT. I get hungry for fat and not much else when I'm out a while.
