Backpacking and survival suggestions

I'm a minimalist when it comes to backpacking and survival. Maybe not the best approach with survival, but it certainly keeps you mobile.

I've been building and revising a BOB for a long time now. It's never perfect. So far, my necessary equipment is:

ALICE pack (main ruck)
Load Bearing Vest (powerbars and gear)
0 Degree Bag
Bivy Sack
.357 Handgun (50rds)
2L Camelbak
2x 2-Qt Canteen
Katadyn Hiker
Smashed Roll of TP and toothbrush
FM 21-76
LED Headlamp
Bic lighters and trioxane bars
Gauze, antiseptic, ace roll
Line, hooks, bobber, splitshot, 3 lures
And lightweight calorie dense food

Anything else is more of a pleasure than necessity. I try to pack:

E-Tool (maybe)
Mess tin
More food in a buttpack
Paracord
Tarp or two
Thick Vinyl Ponchos
Garbage bags
Emergency strobe (better than a flare)
Bug Repellant
Batteries

Always wear polyblend pants (BDUs are good), underarmor shirt, gloves, good boots, and a hoodie.

I do everything I can to keep effectiveness to the max, weight to a minimum and look somewhat civi. I usually end up carrying extra weight to make sure I stay dry and warm, because winter plain sucks. I can always find food, city or woods.
