Been using my Blackland in the Barracks this week. Shaves like a dream. I really can't tell the difference between the shaves with this and my Rockwell 6S. I do get more blade life from the GEM PTFEs. @wchnu , you are absolutely right. The Dorco Pace blades are only good for paint scrapping, if that. I'm glad I brought an extra GEM PTFE with me yesterday morning. If I wanted to get my hairs pulled instead of cut I'd use a cartridge.
