Hi, Bill - great to see your new pack. I used to love my old Jansport, so those hip extensions on your frame bring back memories.

I have a question (OK, a few questions) for you about Cuben packs: where do you imagine that any fabric or seam failure would occur? I know that since you are SUL you probably have not seen anything "blow out" as yet but I'm wondering if I were to make a pack bag for my Luxurylite frame, what would I need to look out for in terms of longevity for the bag? I generally carry 18-25 lbs depending on the trip. Do seams tend to tear through the fabric? Is sewing preferable to taping? (what type stitching?) Looking at samples, the fabric itself seems pretty abrasion resistant - is it?

Good to hear that you are recovering well from still more surgery, and still getting out there hiking and designing equipment.
