Bridgestone has updated its E6—a ball which I have rated among the best currently available mid handicappers. I play the E6 and the Callaway HX Hot almost exclusively.
The updated Bridgestone E6 still is designed to reduce sidespin, keeping the ball in play while producing better-than-average distance. Bridgestone has apparently changed the composition of the ball to further reduce spin, while increasing softness.
