For one of our prototypes we are using 2 kitbot wheels with a taction wheel in the middle (smaller diameter creating somewhat of a 'U' shape). We did notice that we were marking up the ball with this set up so we decided to literally cover all of it in duct tape...it worked! No more marking up the ball and to be honest, I do not think we lost any distance on the actual shot. I sort of looks like a drum now with a depression in the middle. Keeps the balls flying straight and consistent.
