Here's a link to that podcast episode btw if anyone wants to take a listen to it - it talks about Tabac soap, slant razor, etc. And how he went from this: ...to this:
I like my 37C. It is not my favorite, but it is my favorite slant. I don't feel the need for another.
First shave with the 39c, the big brother of the 37c: It's as heavy as my beloved Merkur Futur. The first shave went smoothly. Only two minor nicks. It feels much more mild than the Futur at 3, but it was almost as thorough as the Futur, but still didn't give me a faster shave. Still, I'm impressed how a razor with such a small blade gap can cut through beard so well.
