The shave cream/soap matters a lot. I have been experimenting with foamless shave creams, Cremo, Harry's, and Gillette Pure applied by hand. These seem to provide slicker surface but very little cushioning. The result is less irritation, a smoother shave, and a closer shave than most other shave creams whipped up with a brush. It does take extra care with a DE to avoid nicks and weepers but not really a problem with carts. I can get this better result with DE's, Gillette Flexball, and Gillette Sensor.
