Well just finished a nice shave with the Personna red in the feather stainless, and it was interesting. Very smooth, but very mild compared to loading it with a feather blade. I found myself having to make multiple passes over the same spot to get to BBS, yet had minimal irritation and burn compared to less passes with the feather to BBS. I ended up finishing with a touch up pass with my super adjustable with the same blade set on 5-6. Through my powers of deduction and common sense I am going to assume my next shave with the red in the super adjustable set on 5 should be similar to my feather ss with a feather blade... Yes, I know, I even amaze myself..
