I continue my exploration of Simpson Two Band brushes with the recent addition of a 58, knot 25/50mm. Similar to its cousin - the Duke 3 - in density and knot size this 58 turns out just great in the softness department. Neither the Duke 3 nor the 58 have any (!) scritch to it. They are actually exhibiting much softer tips than the Super 3 bands I also own (GYLE, Duke 3 , Chubby 1). Thus, at least in my experience based on these two (not representative) brushes Two Band hair is the grade to go. In backbone, softness and density both the Duke and 58 are similar to the Thaeter 2 bands I have. Only the XL series (fan!) beats them in backbone. Pics below...
