I have the Saw ones in combination with a set of Formula RX brakes (RX20 to be specific, but they use the same basic parts).
Not too pleased with the setup. The rotor's rings would keep touching the calipers and the washers whenever I tried to set them up just right.
I eventually decided to file away parts of said calipers and washers to create the necessary clearance.
Also, the original Formula discs had much more bite than the Saw ones. That being said, the Saws don't warp and the originals required constant truing.
