Here is a question that people on this board may have an opinion on. For an average Slim, what would you correlate the each of the Slim's settings to the aggressiveness of a non-adjustable razor. For example, I think setting #8 is about the same as a Fatip Grande. Setting #4 about the same as a 1950's Tech. #3 about same as the current Lord L6 (I think thats the model). Anybody else have opinions here?
