This morning was my first shave with my Fatboy. I used a new Astra SP blade and set the gap at 6. It became aggressive and not smooth at all. This is nothing like my Merkur 37G Slant, EJ89, Super Speed, Tech or Aristocrat. I even lowered the gap in mid shave. After I was through I had some weeping that I had to blot out with cold water and a towel. How does one determine the proper setting on one of these? Is there any other technique that should be employed when using this razor?
