Compared to your 6C the Progress is only marginally more aggressive feeling. IIRC the numbers on the Rockwell plates correspond very closely to the numbers in the dial on the Progress as far as gaps go.Thanks a lot, Shane. Much appreciated. I do have a Rockwell 6C and love it.
Hey, who knows ... maybe I'll just go for an Osprey. It is an absolutely gorgeous piece of kit.
I find the Progress cuts in more of a scything motion as well: it bends the blade more than other razors and has a smaller window of effective shaving angles. Once you find the "sweet spot" it's a very efficient and forgiving shave.
