At this point i've settled upon my favorite blades. It seems the sharp, and IP's are my favorite. Recently I have noticed that my shaves appear to be the best when I alternate. It seems if I used the same brand blade for too long (lets say a couple weeks) i just don't get the same level of shave. I can't yet decide if it's just because it keeps me from getting stagnant in my technique, or if somehow my whiskers adapt to a certain blade. That sounds kinda cool.
