Championship Tour Edition 66 1-3/4" Rail Core Mounting Guide
For K-66 Tour Edition Cushions and at 61%, 62%, and 64% Ball Height
NOTE: All angles are predicated on the rail being a full 1-3/4" thickness in front of the featherstrip groove. If rail has a 1/32" cloth relief in front of the featherstrip groove, all angle dimensions will increase by 1-1/2 degrees.
As a result of our intensive testing, we recommend mounting the cushion to the 1-13/32" nose height to achieve maximum accuracy and overall playability of the ball.
