agreed, more or less. especially the comment about liner socks sagging/bagging and causing trouble.
on the other hand, I like to wear boots fairly big for warmth, so a single sock doesn't fit snugly enough.
SOOOO: my system for the past 3 or 4 years has been double pairs of Wigwam Merino Light Hikers. cheap, soft, durable, wearable for several days without 'foot-rot', and nearly devoid of synthetics - fishstick laid it out clear: "never wear a sock with 'max' in the name!"
cheers,
I like to use the very light wt produce bags for a vapor barrier but they do wear out quickly. For longer/colder climbs I like to bring a few extra since they are so light...
