Yes. I can't strop the thicker razors as fluidly as the smaller 5/8 and 6/8 sizes, and because of this I can't get the big razors as sharp off the strop unless I really concentrate. I believe this is the real reason I strongly prefer smaller razors.
I'm exactly the same way. I can strop my 5/8 Dovo special almost like a real barber! heh
However I can't do the same thing with a custom razor that I have...the blade is longer and heavier..
