There is no reason to increase the friction between the clay and the tray Ken because the centrifugal force will keep the clay tight against the opposite side of the tray to the spin direction this will in effect cause the clay roll out rather than slide. Also it produces one of the hardest targets to hit because you will have no idea before you see the target what part of a three hundred and sixty degree circle it will appear at every time. And unless you make the electrical release version there will always be a varying time delay from “pull” to the clay appearing. This was the reason for their fall in popularity no matter how good a shot you are the odds are always stacked very much against you and that does take the reward out of clay shooting rather. It did not earn the name the “devils clay trap” for nothing.
