So today I used 4 on WTG and 1 1/2 on the next two passes. I used a Med Prep blade. The first pass is impressive, removing almost everything. I probably could have left it at that. I'm not sure there is an advantage to being that aggressive on the first pass if I'm going to make two more. The end result is a BBS, but I can do that with all three on the 1 1/2 setting.
