Well, Bob...
You make it sound too exciting. All razors are very much the same. I am old enough to have seen the Magic Hype of the Dubl Ducks. All I can say is a) the Solingen razor makers think they're ridiculous ("our apprentices made them, because the Americans would buy anything, really"), and b)
And you should not. A disorder really is not something of which we should make fun. And even if (and that is, in my very humble opinion, a very big if), there are basically 5/8 and 6/8 razors to choose from. Anything narrower, or wider, than that requires a narrowly defined field of application.
