Its my favorite ball allthough it was my first high performance.
The only other balls I have thrown (besides ebonite demo days) are the Brunswick TimeZone and the Storm SureFire.
With the Xfactor my average roose about 15 pins the first and got better from there.
Now the SureFire is my "go-to" ball because it's new I want to see how it works, I still love my xfactor.
