I'd damn near give a year's pay to have lunch with Gillette's top blade engineer if he/she would simply tell me which blades are duplicates and which in their opinion is their flagship DE blade. Based purely on tradition it would have the word "platinum" in the name. I would love to see a blind test of the Platinum, Rubie Platinum Plus, Goal Superior Platinum & 7 O'Clock Super Stainless. A true duel of the Titans!!
