Hey RockB,
Sorry, just closed shop. I honestly feel this is not a blem or defective, all Track balls are advertised to be precisely pre-spun from factory to ensure proper placement and marking of the mass bias. I personally have an Unleashed where the pin is under the bridge, cg right about 1/4 inch(in palm) and the mass bias is all the way over in my val line already and THIS is the ball I shot 300 with. I laid it out accordingly, from simply where the markings were and I'm getting exactly the reaction expected. I don't believe you have anything to worry about, just make sure you drill the ball according to the markings of Pin and MB.
Based on what you stated, your ball is drilled to go somewhat long
(mb by thumb). As Excaliber, Chapman, and myself have mentioned quite a few times.....PLS becareful with the mass bias positioning. It is extremely important and crucial to creating the desired reaction in Track asym. cores.
I realize it looks different but it's simply another version of imbalance(maybe the weightblock shifted a little while settling, not sure). When Fab first messed up and ended up with a pin out ball(hammer), they thought it was a blem. Everything back then was supposed to be in the grip center, pin and cg. They didn't even know at first what they stumbled upon and were about to create. I'd rather see a marking off then just stamped there and not really be in the right spot because then you wouldn't get the proper reaction. The only down turn to these balls I've come across is that I have to watch static weights as they can shift in directions that I don't want for a customer. Hope this helps Rock but feel free to contact me directly and I'll be more then happy to help you.
Edit: I'm supposed to meet with Mark Baker tomorrow, I'll ask him too.
