Bob,
Thanks. I consider my vintage razors to be fine razors. I like them very much (but they do need some slab work though).
I am not expecting a better shave from a new razor, but I hope I find that I enjoy the shave more with a heavier and less hollow blade...only one way to determine that;) The only one I have that is not extra hollow is a very shallow profile (perhaps 3-4/8). I love it, but it does not answer the questions I have about a more chunky blade in a 6/8...or perhaps 7/8.
The reality is that I will probably rotate razors. I have already shown that trend. I am a tinkerer and a tester...anyone that knows me from the knife forums knows I am constantly dinking with things trying to make them perform better. At this stage of the shaving game, I am acquiring knowledge and experience and I think I will be happier buying some variants to play around/experiment with.
