Derek, I have that D-way CBN wheel, except the radiused edge one, and love it. Fast, cool, and always ready with no fettling. I haven't felt the need for the coarser wheel, and it's so smooth, I don't want to put anything on the right side that will add vibration. The picture to the right is with it running, and I left it running like that to go to the truck to get the camera.
