Sorry, I should have taken a closer look! As I mentioned, though, pack features depend on individual circumstances--what works for me may not work for you--and vice versa. It's YMMV and HYOH, again!

Please keep us informed about how the pack is working out for you! It looks to me as though you're onto a good thing!--perhaps the start of another cottage industry in our area?
