Hiya,
Years ago I started my DE journey using a super adjustable. After some trial and error I found the right setting and kept it there. Same thing with the slim that I used steadily after trying one. Heh, the slim took care of the super and it was put away, although the perfect # setting was the same on both. After that I tried a fatboy and put the slim away to never be used again. Same # on the fatboy though.
I am in the 'set em and forget em' group. No reason to screw around with all around perfection. Sure, I might get a little closer shave if I bumped the setting up a few notches on the AGT pass, but the comfort level would suffer a bit. Even going WTG I would still feel the blade on my face too much for my liking.
