I've got a 15lb used Rock Star. It has NO TRACK. Low games. It's got a 1.5" PIN from the CG. Been fully plugged and redrilled one time. The old drilling had the PIN above the ring finger and the CG under the ring finger, and the current drilling has the PIN under the ring and the CG stacked directly under the PIN. The plug work doesn't match the ball, the plug is black in color.
There is no track and the ball is very clean as far as wear and tear.
Interested in it??? Make me an offer I can't refuse...
