I am the fortunate owner of the Mongoose SE Razor. I have been reading all the forums and don't see much mention re the use of the Pro guard blade in this razor. I have over 100 of these blades so I don't have anything else to compare. Am I missing something? I get an excellent shave but am wondering if I could do better with the Pro, Super or the Kai. I would really appreciate your comments on the best blades for this Cobra Killer.
