Brian, Think about these ideas.
Put the mini bic in your pockt. Change the fishing line to thinner spiderwire. Scrap all the Band-Aids and get 2 large Band-Aids with antiseptic on them. You can use larger Band-Aids on smaller cuts if needed. Toss the oven bag and the condom, use the zip--locks for water. Keep the condom if you think you might get "lucky". Why 2 Ferrocerium rods? Scrap the Small Ferrocerium Rod (From Doans MFS) you can cut back to 8 or even 6 tinder quicks if you want. Same with the REI matches. You can use the fishing line (maybe not perfect) in place of the black thread. The fishing prerig is redundant, with the line, hooks, weights and bait you already list.. Cut the dental floss down from 100 feet, same with the spider wire. Any of these might reduce the size of your kit, and not lower the capabilities of your kit too much. Then again, I could be talking out my tail feathers.
