I think I will try to go with the following, depending of course on space:

Behind the insert:
Starflash mirror
Jetscream whistle
2- 4”X 6” Heavy duty Ziplocks or milkbags

In the pouch:
Paracord
Mini-Bic lighter
Blastmatch, metal match, or ferro rod
Wetfire tinder
2- 4”X 6” Heavy duty Ziplocks
Repackaged Potable Aqua (or I may finally try out the Chlorine tabs)
Allen wrench

In the handle:
Fishing kit and snare wire (both currently residing in my PSK)
Sparklite and tinder

With the exception of the fishing kit and snare wire, this will all duplicate stuff that I always carry in my wilderness PSK.

Again, thanks for all the suggestions, especially Schwert and dchinell for the links to that "SASS" page--I have bookmarked it for future reference.
