Nice pic Bob, you may want to consider posting it in our new Photo forum as well.

As for a pack, you are right, it's all about fit. I used to have an old TNF pack I could wear all day. I like the fit of the GG packs, although I've only worn them in the store. I have a Kelty that fits me pretty good, but some day, getting a new one.

I had a big Arctery'x Bora 80, but the belt and straps were so stiff, it was really uncomfortable-got rid of it after one trip. Seemed okay in the store, but not in the field fully loaded. I would definitely try before you buy if at all possible.
Don't get me started, you know how I get.
