This ball was the ball that Track was ready to release but then decided to scrap. A bunch got distributed to various proshops who then sold them. It's supposed to be a very good ball, it's a particle from Track, but not a hook monster. I haven't thrown one so I can't give my opinions, but wait for Rick Leong (tenpinspro) Anthony Chapman, or the various other Track experts on this board, they can give you more info than I could.
