Cutting the 550 cord down to half and replacing it with 100lbs dacron seems like a good idea. There are just so many uses for cordage. But alot of it is under the 100lbs static load mark.So the space that would gained in the pack would be a plus.
I EDC a leatherman wave and a benchmade folder (and my sidearm of course).Thought this was sufficient with the juice as a backup tool/knife. Another thing that slipped my list was the razor packed in my fsk.
Can you tell by my fire starting means and tinder kit I put fire way up on my list(not the top however)....this is my paranoia in kit/survival situation.
