I was getting cold, and, well, after reviewing the tape, I think I could have prepared the tinder a little better. But, the cotton ball lit right up.
As for the 3/4 Z-rest; I had clothing stuffed into the bottom of my bag, to both warm them for the morning, and to keep my feet from direct contact with the ground. I think, all in all, it was too cold for the bags rating. I did flex my thigh muscles throughout the night, to warm them up. I am thinknig that adding hand warmers to my it is gonna be a definite. It took about 15 mins of walking to warm my toes!
