Hi Jack, awesome weight reduction my friend! You're at a point now where you need to take this gear out on a trip to see how everything works for you. 12 lbs. is a pretty light baseweight in the grand scheme of things, and as long as you are comfortable and warm, you're gonna enjoy packing alot more. Gear thoughts:
- Keep the dental care and soap if you want. We're talking less than 4 oz. here, and long term repercussions from deferred maintenance on your teeth isn't worth saving a couple ounces.
- There are alot of lightweight options for pillows. Try this: partially inflate your Platy and wrap it in something soft. Haven't done this with a Platy, but it works well with Nalgene Cantenes.
- Spend a night out in your yard with the CCF pad. Some can use them and be comfortable, others need something thicker/cushier. Don't sacrifice sleeping comfort for a few ounces! If you awaken stiff, sore, and unrested, you won't be a happy camper! A nice pad is the one place I'll carry a little extra weight, but it's a decision you have to make for yourself.
Now that your pack weight is significantly less, the decisions you make about gear (replace with something lighter? Don't take at all?) will have much less impact on the weight you're carrying. Make a list of everything in your pack before you leave, and anything you don't use, leave it out next time. Needless to say, this doesn't apply to meds and especially the EPI.
Have Fun! That's the whole point here, and I bet that lighter pack is gonna increase your fun potential exponentially!
