How are the sock stuffed shoulder straps. Do they feel like they will be comfortable with a fully loaded pack for long periods of time. It seems like they would be lumpy and create sore spots, although I haven't tried it. I always thought that was part of the design was a little extreme. Again, I haven;t tried it, though. Curious to hear your about your experience with them.
Congrats, btw. I made a pack last year, my own design, and it wound up being a POS.
