I'm wondering if Fatboy users have a 'go to' blade? I had en enjoyable past few days with Rapira set at 5,5,7, but not Permasharp, which for me seem to work only with the slim...and today's fresh Gillette super platinum felt great. I no longer use feathers frequently on the fatboy. Also, I tend to lower the settings with Gillette super platinum and Feathers, all the way down to 3 ATG, although I tend to set at 5,5,7 with what I feel are smooth and less aggressive blades like Rapira. So for me, Rapira and Gillette super platinum stand out as regulars with different settings
