Everyone has their own ideas about kits and gear in general -- what works (for them), what doesn't work (for them), the best way to carry (again, for them). It's rare to find a one size fits all kit.
I don't believe in one-size fits all. A person needs the tools which works best for them, for the environment they will be in. Recent circumstances has caused me to rethink what I carry and has taken me somewhat further off the path Doug Ritter laid out. Granted, I am considering some of his ideas I have not implemented before such as a Fox 40 and a Photon Freedom Micro. Is what I have on my person, at this moment, the best gear I need for an urban environment? No, it's not. I came back to this forum because I have to rethink what I use in an urban environment.
