The main thing is to do whatever works. I don't use the pyramid method at all and prefer the smallest, tightest, scratch patterns and, therefore, micro-serrations I can possibly get. Every razor has microserrations; it's just a matter of how fine they are. There's little point in using a steel with a super-fine granular structure if we actually want teeth on the blade and yet, the cryogenically treated steels tend to give superior edges and one of the characteristics of these steels treated cryogenically is the very fine and even distribution of carbides.

Japanse Feather blades are the sharpest things I'm aware of mankind ever making and I think they're outstanding double edge blades because of it. They shave effortlessly and the straight razors I like to shave with best shave almost as effortlessly and cleanly. I'll admit I don't get them that sharp, but I get them pretty close and that's always my goal. If my blade has to have teeth on it, I want them to be as small and fine as they can possibly be. At least that's how I feel about it now. Tomrrow... who knows.
