| Maxfli Mixed D-Tec Extra Spin Practice Golf Balls - Golf-Balls - The new D-Tec Extra Spin Distance was designed to deliver the extra yardage you’d expect from a distance ball but with the kind of soft feel and high spin-rate off the irons that you wouldn’t expect. How were we able to combine such seemingly incompatible performance characteristics? The key is an exceedingly high-energy distance core and the way it works in concert with the soft-yet-durable Surlyn cover that features a 442-dimple pattern designed to launch at a high angle and to knife through the wind. |
