Just got me a few Gillette Silver Blues... After one shave... they might beat out the Blacks... We'll see.
Probably explains why my waistline keeps expanding as well. Lack of willpower.
Silver Blue are the best blades I have ever tried. I have 7 O'clock yellows which give me a good three days, but GSB can give me a good five shaves.
I'll probably PIF them when I get a chance...
