So I've worked through a number of blades from my sampler pack and have my 2-3 favorites. When do I stop trying blades? Do you guys settle on a single blade or do you rotate? Do I keep the blades that didn't work just in case they might work in razors I acquire down the road? For whatever reason I am not into sampling blades the way I am creams, aftershaves, and colognes. I sort of want this part to be over. However, I don't want to stop too soon and possibly miss finding a better razor/blade combo.
