The 900 Global line introduces its newest urethane entry, the Zen U. The Zen U features the all new S35 Urethane Plus coverstock, and the highly successful Meditate symmetric core. The Zen U in 15 pounds features a RG of 2.56 and a differential of .027. I drilled my Zen U 4 x 4 x 2, just a basic drilling which puts the pin above my ring finger. The Zen U is not your grandfather’s urethane ball. The Zen U reads the lane early just like most solid urethane balls, the difference with the Zen U is the continuation of the back of the pattern. Where most urethane balls just keep going forward, the Zen U definitely has a more arcing backend motion. As I do not drill many urethane balls and this is the first Global urethane I have thrown, it is hard to compare them. However, I can say that I have drilled a Pitch Black and a Pitch Purple. For me the Zen U fits right in between these two. It reads early like the Pitch Black but has a little more left on the backend but not as much as the Pitch Purple which for me was more like an entry level reactive reaction than a urethane reaction. The Zen U will be a great go to ball on the short sport patterns or a lighter oil condition where you are looking for a controlled reaction. This ball does not lack in hitting power for a urethane ball. Being able to stay right, I was able to throw messengers at those “urethane†corner pins that stayed standing.
