At least now, Eric, we don't need to go in disguise when we take our jetboils to the back country. The weight of that false beard was killing me.
In general I think you're right; there's a kind of pendulum swing, where you look at how absolutely light can you go, and then consider what you might gain by "spending" a few ounces--use a 9 oz Neoair vs. a 3 oz piece of foam, avoid back surgery, that kind of thing.
Clayton--I've also had problems with the igniter on my Snow Peak GigaPower GST-100a. For long periods of time the igniter won't work, then one day it will start working again, for no obvious reason. So, like you, I have to carry a back-up Bic.
