Energy is designed to resist power and headwind. It will handle the hardest throws into the hardest winds and yield predictable golf flights. As the overstable bookend to the 23mm class, Energy shares its core and shallow dome with the Nitro. When you’re going for max distance above all, added dome and glide is useful — with the superb line-holding properties of GYRO™, the Energy is able to take advantage of this glide without sacrificing its wind resistance.
