Brian:

Nice rig. You've got all the major bases covered, and others have already made the suggestions I'd make.

Mostly, I was wanting you to move the "handy" stuff outside the tin -- like the LED. But that might conflict with your desire to detach the tin and use it separately.

I don't know about adding hunting/gathering stuff. If it's just for six days, will you really be fishing, or setting traps? Maybe some glucose tabs to get you over a rough hour or two. Maybe some tea bags to pick up your spirits -- but what to boil the water in?

Finally, you seem heavy on plastic bags to treat water with. Maybe you could sub some of them out for a light silnylon or net ditty bat. That way you could carry water, foraged goods, or dump the kit stuff into it for handier use in an emergency.

This never ends... What a hobby.
