Track Tour X Solid - This is a unique ball. Not many balls have ever been created with the similar specs of high 2.58 rg, 055 diff. For me, this and other high rg balls like the storm fight series extend the pattern/break point. Meaning when the lanes are hooking and the ball wants to pick up and take off, these high rg balls glide an extra few helpful feet. When they work they are great as it is a shape other people may not be able to replicate but they are terrible sometimes as well. I have found I can easily tell if it is the right ball for the moment wirh a few shots. I would use this as a specialty ball addition to a core arsenal. Or if you happen to bowl on a hooking house shot or throw the ball on the slow side it may be a good overall option. - Switched to 15 so selling all my 16s. Chk my other listings - Bit of plug around fingers - Large Vise IT installed 1/16 rt 3/16 rv - Not many games on this one maybe 15. - I'm a pro shop guy so ask any questions * I also have a Tour X Pearl that I will post at some point or possibly put the two together.
