Thats made the ball more stable in flight. But the biggest advance has been the proprietary Speedlock core, which is essentially a waffle-iron like pattern on the cores surface that locks on to the layer above it promoting better energy transfer. The company used the analogy most Canadian can understand like a snowtire in winter. More grip, less energy loss which means more distance and control. We knew we hadnt pulled 100-percent of the energy that we could out of the existing RZN core, says Rock Ishiii, Senior Director, Golf Product Development, in a press release announcing the new ball technology. Working in partnership with DuPont we were able to develop a softer and faster RZN material and created the interlocking core design to reduce energy loss at impact. That means more distance, especially with fairway woods, irons and wedges, and softer feel and sound around the greens. One of the other benefits of the ball is how it sounds Ill write that again how it sounds. At the companys launch of the new ball, both Rory McIlroy and Paul Casey commented that what they hear when they hit it especially on shorter shots is truly music to their ears. Im finding that especially around the greens there is a big difference, McIlroy said in the same release. The ball feels and sounds a lot softer. And even from inside 50 yards, it felt like the ball was getting a little more grip, a little more spin.
