Unless there are any objections, I'll keep this thread going with updates from time to time concerning the evolution of the life vest above. After more research and comparisons, Doug Ritter's article is spot on in several ways. Specifically, I'm going to follow the same recommendations and attach the following LED to the zipper with a gear keeper (shown below)...
Keychain Light - $10
(Waterproof LED light w/ changeable batteries).
Gear Keeper - $25
(Attaches to vest and holds items, like LED light, on retractable cable. I'm also going to put one of these on the right hand side to keep a Seat Belt Cutter in easy reach).
E2E Flashlight - $95
(6 volt lithium system - very bright).
Now, I'm down to deciding on a folding knife, pyrotechniques, and mini-survival kit. I'll look into the thermal suit. Thanks for the feedback... keep those recommendations coming!
