Really like Maxpedition stuff I have, need a small fanny type pack to replace a very old and worn out The North Face pack. Over the shoulder will not work for me at all, period. So, I like the Proteus, but always need more room. I don't have any where to try these myself, so I was wondering if the SabreCat might actually be too big for practical use. That is to say, fully loaded it might be to heavy for around the waist. I use my bags like this mostly as tool bags, a few tools (heavy), zip ties, flashlights, just general use stuff. Any thoughts, as the SabreCat is twice as expensive, I don't want to just buy both and see.
