Have any of you tried the Track Alias yet? If so how did you drill it, symmetrical or asymmetrical? I have mine drilled symmetrical and so far I have not had that much luck with it. I have not changed the surface yet, been throwing it at out of box to see what it does. Going to put it on the spinner today and modify the cover some, not sure by how much yet, but was just curious as to what others have seen.

Welcome to BowlingChat

The "Symmetrical" drillinjg recommended by Track is outside the recommendations for the Dual Angle System.

The Negative Drilling Angle basically takes the core out of the ball motion. The core will not "rev up" because the spin axis will not cross the Pin to Spin line.

Coverstock prep will be essential to getting your ball motion where you like, if you can even achieve good ball motion.

If you would have posted prior to drilling it I would have advised against it. Why spend extra money on an Asymmetrical if you are going to drill it "Symmetrical" anyway.
