Didn't really care for the 300's...haven't tried the 301's as I have found that Feathers work quite well for me, so I think I'm done experimenting on various blades.....well, and I mostly use straights anymore, so I haven't much need for all those DE blades lying around.
I'm not a fan of the 300s, but haven't tried the 301s yet. They seemed to pull on my face. My preferred blades at this point are Swedes, but my go-to blades are Crystals and Red IPs.
