Fellas! OK, in the mail came a 1967 Gillette Ball-End Tech and a 1970 Gillette Super Speed. After a rigorous cleaning, I had them loaded with new shrapnel and ready to go. Now, how is a man supposed to decide between the two!? I started the shave with the 1970 SS and finished with the 1967 Tech. I had a lot of fun trying them both BUT... I am still a tadpole to DE Shaving, did I break a hallowed code or anything? Is 1 shave 1 razor an unwritten rule? Curious... -wolfey
