Shooter Track Material - grippy or slick?

[jvriezen]

On our linear belt driven shooter, we found slick went further. I believe it is because we got higher velocity and less (but sufficient) spin as the disc slipped against the slick surface. We hope to gear up the belt speed and may need to try again. But then again, we used one other trick that is likely relevant, but that's a trade secret -- haven't seen it in any other shooter videos or descriptions.
