I went back to the Derby's tonight and instead of my HD I took out the 71 ss It was very smooth it is amazing how different the blade acts in a different razor
Good to know, I will need to throw a Derby in my SS....although, I only have the 40's SS...I have been alternating between Feathers and Crystals lately when I use a DE.. There's some cool new blades in the TSD store I want to try too....
