My first X-Factor, First couple weeks the ball hooked outa the house, but after about 30 games it calmed down, and turned into one of the best balls i've ever thrown, very predictable, and just crushed the pins. My second Xfactor had a completely different drilling but was about the same, awesome lane reaction didnt matter the lane pattern.
The one ball i wish i could find again, is a Tour Power with a 3 to 3.5 pin and 3.5top weight The one i had, was a short pin, but read the lanes so easy it was stupid.
