Picked up a Shadow last weekend and have been putting a few games on it every evening. I have been getting air balls often when missing the left ramp. It has been happening less as I have been getting better at hitting the shot, but all bets are off when multi ball starts. I plan on replacing the flippers and rubbers this weekend as the current ones are in bad shape. Will this help the problem or is it just natural to get air balls from that shot?
