Don, I got the Normanskill at the ridge, I have only ever worked a few other pcs of this material and I was still pretty new so I only bought a few pcs because of earlier experience with tuff material. Sure wished I would have bought a few more it worked a lot better than earlier attempts
Thanks for the tip on on angling the corners and I believe you are right about asymmetrical being from lots of reworked edges, Just about every example pics of Perkys are made of the yellow jasper, BJ, Steve and Eddy all you need to come to the Ridge is your sleeping bag and your credit card, got lots of room in the tent and we eat like kings. Oh maybe ya better bring some earplugs, lots of snorers, but not me
