This one shows the radial cuts in the bowl pads - hope it shows. the flats are on the SR200 right now. the VWAPs are the yeller ones of course.
And just to show you - below the flats and bowls are both on the side so you can see one is fatter than the other - but BOTH have radial cuts in them. Interesting Joe Grado predicament, no?
