Originally posted by Lowell Goudge you also need to consider the back pack for the tripod.
Most packs have tripod straps on the front. this puts the weight a long way off the body.
Look for one that takes the tripod through the center, flush wity your back, or on the side
I expect that's pretty good advice for camera specific packs. When you're backpacking or something similar, however, you fit the tripod to whatever pack you've chosen to use, not the backpack to the tripod. If you think photographers are fussy over camera bags, you haven't seen a serious back country type trying to pick out a pack to suit their style and needs.
I have an old internal frame custom backpack that I had made by Schonhofen in the early 70's. There are lighter and more waterproof backpacks out there now, but after laying it out to my specs, having it fitted to my body, customized here and there with pockets, dividers, etc put exactly where I wanted them... I've never had anything remotely as good. It's about worn out now and I would love to be able to get the same thing with the new modern fabrics and waterproof zippers.
My Slik usually rides vertically on one side of the other of my internal frame pack. I imagine its replacement will do the same. When I'm humping gear on the external frame, it gets secured under the bottom platform. And when I'm humping the survey tripods, it goes in their bag with them - lots of leftover room. Some of my buddies put their tripods in with their sleeping bag, but then you have to deal with the tripod every night and when you want to use it you have to unpack your sleeping bag.
I have seen some trekking/avalanche poles that kind of, sorta, convert into a camera support of sorts. I've always thought that the only person that would be happy with those setups would be somebody that was happy with a monopod, because they really aren't any better.
