Looks like an awesome progression. The Barber's Delights are legendary-wish I could find one on Ebay for less than 5 Benjamins, though.

I did finish that last Crown and Sword rescale on the Zulu Gray with 4 Escher slurry dilutions with about 20 strokes apiece (using my 1x5 Celebrated Water Stone as a slurry stone), then 20 more apiece on plain water, then with a drop of Dawn, and finally with glycerine and water. Stropped about 200 strokes across my rack of shells to cordovan, and she feels about perfect on my finest arm hair. Will test shave tomorrow before giving it to the young man I mentioned. Lately this technique is giving me my smoothest edges.
