1. if properly Hydrated SV
2. Where' PAA CK-6 from your list? also no mention of the PAA cube 2.0 pre-shave/soap mix
3. Stirling Sheep
4. Cremo (not a soap but a cream)
5. any soap with shavings from a PAA cube 2.0 and a 1/2 pecan size amount of cremo added to it before mixing.
Slickness in soaps is difficult to quantify- it is, after all, soap which is inherently slick. All of the soaps in that list are good slick soaps. And, of course, there are lots more.
IMO, I don't notice much difference in slickness between soaps when loaded generously. Some like Tabac/MdC load very quickly and gives the impression of better lather, but a dozen more swirls with Arko and I get the same results.
