I had worked through a sampler pack of blades from WCS and finally settled on Astra SPs as my daily blade. 2 weeks ago, I loaded a Feather and got a really close shave, better than with the Astra. Did the same thing today. I can't imagine my technique is that much different. Same razor as well- 59' Fat Boy. Anyone else out there notice they get a closer shave with different blades?
