Just wondering if the pop bumpers on my TSPP are functioning correctly. They don't seem to be as active as I thought they would be. The balls seem to bounce off of them without triggering the bumpers quite often. Unless it's a hard direct hit they don't seem to work. For example, when I shoot the right orbit, the ball exits directly onto the left pop bumper and it usually does not trigger. That just doesn't seem right to me. Is there a way to adjust the sensitivity of the pop bumpers? Or, is this just the way TSPP plays?
