Appreciate everyone's comments on which of my blades to try next. But now I am wondering what people's experiences are with how many different blades to get in "bulk." For instance, is it reasonable to assume that one blade will work better in a given razor than in another razor? So, if I have two different types of razors, may I guess that perhaps I would prefer to have a different blade for each? Perhaps one brand for my SS and another for my Tech? Thanks, John
