1-nothing it is useless except for buffing one's secret parts. Maybe. 2-Feather Popular 3-Gillette Tech 4-5-Super Speed 6-7-Red Tip Just a rough guesstimate of course.
I haven't tried any DE razors that look/feel like a 9 which is why I left it blank... The gap on 9 seems bigger than the Red Tip's gap. They both have pretty small blade exposure- about the same. Also the blade exposure on the Red Tip looks exactly the same as a regular SS- it is only the weight and blade gap that is different. I'm sure most people will say the Slim isn't that aggressive anyways on any setting. Anyways treat my answers with a grain of salt. I don't think ,for example, with the Tech which is a three piece design with a different geometry translates really well to a TTO one.
I thought I read somewhere that a adjustable set on three was about like a normal tech please correct me if I'm wrong
