Simple question, Jim- when you look at that, while you can undoubtedly see things that can and probably be should improved on, is there something you didn't cover?
Actually, looking back the thing I was missing was something to cook and store water in (no HD aluminium foil)
The real question is, could you use that gear then?
If you mean: could I survive using this gear?' the answer is yes, I could. But if I look at my current PSK,BOB,EDC,FAK,etc. It all is based on this kit, so as you said, it's all a refinement.
As for setting up a forum and writing books?? Only time will tell..
