Hi! The club I shoot for on wed. has an Imperial International Eliminator. Balls hop off the rails if hit with even a moderate stroke. I measured the height and it's 1 1/4" to the middle of the radius of the edge. Is it possible to adjust the rail to 1 7/16"? Is it possible that the wrong rubber was used? The table is a couple years old so it's kind of up to us to fix it. Any advice would be greatly appreciated. Thanks!
