Yeah the bushwacking tools stay home for certain trips "Leave no Trace Hikes" and will save over 2.5lbs, but for trips with designated camping areas the scouts camping trips and our canoe trips on the Delaware, I'll bring them.

I think I should be able to get everything in the Gorilla, was hoping someone had experience with this pack and could give me an idea if the gear in the picture would fit in the GG Gorilla

from a numbers point of view I should be ok, however I prefer real world opinions.
5 gallons = (5 x 231) = 1,155 cubic inches
Gossamer Gear Gorilla 2400 ci + 600 ci

I will most likely order the Gorilla and tweak my gear to fit.
I'm afraid if I get the larger Mariposa, that I may take advantage of the extra space.
