I agree! A man don't need to change the variables to much. Oh yeah I like the slim also! The only thing I don't like at the higher settings is i get a bit of blade chatter. I do think I need to finish off on a higher setting. I usually start off mild to mow the bulk down, then go mid-aggressive, and finish at a low setting. The shave I last night with the slim I finished way to low. I think I will finish @4 next shave. I think I will still use the same Derby blade. Definitely not the sharpest, but sometimes I don't always go for the sharpest blade. I have these to try: Crystal, personna lab, Gillette Yellow 7 0clock, Voshhod, Gillette Naucet, Gillette Rubie and Polisiver.
