For me, the best way to carry a tripod and scope has to be one where you can get it into action quickly. I don't think that this rucksack style carrier would do for me, however comfy it is.
There are qualities that people look for in their equipment, the main ones are -
Ease of use
Comfort
Quality
You have to compromise.
I do a fair amount of "bushwhacking" and need to present as small a profile as possible. I always carry a small pack over my left shoulder on my right hip, it has everything but optics - cleaning supplies, two water bottles, bug spray, guide(s), TP, pepper spray, knife, flashlight, notebook and pencil, food, and drugs (athsma).
My tripod came with a "backpack case", not secure enough to use with a scope attached, but which centers the pod on my back and allows me to balance the weight of my other pack, with the scope under my left arm.
I top this off with my bins, the only thing on my neck, and I am balanced and ready to go anywhere. I am surprised how quickly I can erect the scope/tripod in the field...but it's still a compromise.
When the thoughts of taking photos come to mind (which they do, more and more often), I get queasy...
With the thought, "Does anyone else go with you?", I may have to place an advert...under "Sub"?
Oh well, I'll figure it out,
Keep looking up...or down..(wherever they are),
