I wouldn't worry about calling this one from the ashes scoutmaster. A discussion on wool and woobies is timeless and will probably come up many more times. I have carried both backpacking, but not for long trips, because of the weight, and even the short hikes got awful rough. It's all a question of priorities. If you are on a limited budget wool may be the way to go, but you will have to trade the weight off in other areas, or tough it out(which is rarely fun). I use the poncho liner, woobie, and wool blanket for ground camping, which i haven't done since discovering hammocks. Putting wool between the layers is a good idea. Now that I have a double layer hammock I may have to try this sometime.
Go confidently in the direction of your dreams! Live the life you've imagined. As you simplify your life, the laws of the universe will be simpler.
