Dropping 2 lbs for $230 works out to around $115 a pound, which sounds steep until you actually carry the thing up a pass. Your knees do not care about the price tag, they only care about the weight. I run the same math on every piece of gear before I buy it, and the stuff that saves weight where it counts always wins. Sleeping warm at 11,000 ft is the real test too, because a light quilt that leaves you shivering is just an expensive way to have a bad night. You did fine.
