Hey JR, just curious if the Storm Pitch Black is pure Urethane? Also, is there any modern Urethane ball that is pure? Or they all have some sort of pearl/hybrid additive added to their coverstocks?
As a UC3 owner I don't really see a compelling reason to pick up a Zen U. If anything, I find my UC3 to be a little stronger out of the box than I needed it to be. I ended up taking it up to 3000 grit to get the reaction that I wanted.
