I've been using my Slim set at 3 for quite a while. Tonight for some reason I got a wild hair and said what the heck, I dialed my Slim up to 9 and slammed a Feather in it and......WOW!! What a awesome shave. I can't stop faceturbating. I'm curious, has anybody else experienced a Feather on 9 in a Slim? and got a real good shave from it?
