I've got 1 Used and 1 NIB Track Champ. Both 15lb.
The USED one has got a 3" PIN and is drilled stacked leverage. Right Handed. In great condition! Finger inserts and thumb slug. Middle finger was plugged and redrilled in same spot, and the small little part of the plug that is showing is matched up perfectly to the color of the ball - it's hardly noticeable! No track. Never resurfaced.
The NIB one has got a 3" PIN and 3oz Top Weight.
Used ball's price: 40.00 with shipping already included.
NIB ball's price: 60.00 with shipping already included.
