Everything beyond C-5 is just my pipe dream. As far as I know that is.I still strongly prefer a (significantly) larger handle/brush than the C5, however....I need to eat a bit of crow, at least in terms of me proclaiming that this might be "a bad impulse buy."
I know, only a sample size of one, but dang...this little guy (again, with finest badger knot) is a lather-making machine. I just wish it was more comfortable in my hand...again, too dang small. So we feel confident larger brushes in this style are coming? I agree, a C9, heck, even a C7, would be very welcomed. If a C9 comes out, it will be an insta-blind buy for me.
