Chuck, I'll soon be 80 and I've been wearing custom hand made boots since I was 20. Have about 14 pairs at last count. Regarding my boot making, no I never did, but I spent several years and one concentrated year at the elbow of Don Atkinson, Master boot and saddle maker so I am very familiar with each and every step of boot making from the measuring of the foot to the final polish of the boots and everything in between. There are many steps in the boot making process that lend themselves to other disciplines, for instance my inlay method is taken directly from the method used for boot tops, and of course, the lining method is very similar. My techniques are an amalgam of things I've learned doing many things, just as you.
I talked with Roger yesterday and I have several of the vat dyed backs headed this way. It will be good to not have to square up the sides and figure out how to use the best parts of the belly. At least 50% of the belly leather is useless for me and the relatively small increase in square foot price to go up to the backs, I think will be well worth it. Based on your and Sandy's endorsement, I'm sure I'm going to really like the leather.
