Does anyone use a "survival pouch" based on what Wiseman's SAS Survival book recommends?

I pack my DR Pocket Survival Pak along with me one in the house, one in the car, and then when on the trail use somewhat of a "Survival Pouch" that can fit in any daypack. I keep it handy in my car with my large car kit. It can be worn on my belt if I am not toting a daypack or has a sling to be attached. I have a good BOB, but this is sort of something that I "throw" into any daypack I carry along with canteens or Nalgene bottles when off the pavement. I am about fed up with hydration bladders. I am not an ultralighter. The pouch is made to be a utility pouch for hunters and has a sling which can be used with it also.

It contains:

*A US Army mess kit which fits nicely.
The mess kit holds many loose items such as coffee and tea, hot chocolate, gatorade powder, energy bars, small film canister sealed with matches, utensils, spare flashlight batteries and many other things and it slides in nicely to the pouch.

*Coughlan's esbit-type stove and pill-shaped Coughlan's fuel tabs. I found a great way to store extra fuel tabs is to use a round tubular toothbrush holder, the kind used for traveling. I just fill it with the tablets and duct tape it in the middle to seal it.
*Swedish fold-a-cup
*Orange 55-gallon drum liner
*3 ft. of orange duct tape
*space blanket
*orange flagging tape
*sponge
*Smith's diamond-coated honing steel
*small FAK (everything covered on that one)
*haemostat
*dental floss wrapped around every kind of needle you could think of
*wire saw with rings
*6 tylenol extra strength
*my emergency meds
*Immodium
*Claritin antihistamine
*candle stub
*15-20 ft. of stainless snare wire
*Very ample fishing kit (overkill in my opinion)
*salt tablets sealed in ziplock
*Water Purification tabs
*Ferro rod
*P-38 can opener
*Silva map compass
*Small flashlight (varies)
*Extra liner-lock knife (varies)
*Plenty of tinder (I am ridiculously tinder-obsessive practising fire-lighting skills all of the time when out, my daypacks have 5 different kinds - pj soaked cotton balls w/ or w/o magnesium shavings, Coleman fire starter sticks in tin, char cloth in ziplock, cedar bark in ziplock)
I pack and repack along everything else that I can cram into ithe pouch including items that cannot fit into my DR Pocket Survival Pak.


My EDC:

*MkII Photon Freedom Micro light
*Original RSK Mk I knife
*Leatherman Micra
*2 days worth of meds
*pill capsule with emergency meds around neck
*Fox 40 Rescue Howler
*Cell phone
*Red bandana

Alot of the time I have a red Columbia Sportswear neck bag that I put the PSK and a larger multitool and some of these EDC things and more into.

Everyone kill me with criticisms and suggestions, but remember I like this supplemental kit to my Pocket Survival Pak and it works for me. I am not asking for opinions on anything else that I would fit into my daypack or any opinions when it comes to BOBs or carkits, etc, that would be wasting our time. Don't go overboard, I JUST want to work on the contents of a small "survival pouch" (not pack or bag) and find out what I need and don't need when already packing my DR Pocket Survival Pak and EDC.

Some thoughts:

I am open to get a larger OR smaller pouch, I'm not stuck on this one.

Can a aluminum foil mini-loaf pan be used instead of the mess kit to save room?

Has anyone tried boiling water in a empty coffee vaccuum packed bag? If so, how?
