Hammer Extreme Envy Bowling Ball

Big hook and no stop on the backend; that’s Extreme Envy! The first Envy handled heavy oil easily, but bowlers have been asking for more pop on the backend, and we’ve delivered that with the new Extreme Envy. We started with the Envy cover and added carbon fiber; this addition has created a heavy oil ball that does not quit on the backend. Extreme Envy has a different core than the original Envy, this version of the Launcher core has a slightly lower RG and was created to match the Envy CFI cover perfectly.  Everything about this new Envy is Extreme; you’ll be extremely happy with yours whenever you need lots of hook!
