The Chemical X is a good addition to the 900 Global line. It give a distinctive different reaction to what is already in the line. In box finish it will handle med-med/heavy patterns depending on rev rate. Easy through the heads, mild mid lane read, and a smooth reaction downlane. The Chemical X is not a ball to cross many boards the more online you can keep the line the better the ball will go through the pins. Smoothing the cover more and even a little polish will give more length, but will still allow for a arcing type reaction. The Chemical X will fit many styles. On dryer lanes it will be better for higher ball speeds. This is a reaction that all tournament players will need in the bag.
