Ping Tyne 4 Golf Putter 2021 The Tyne 4 2021 Golf Putter by Ping features a distinctive design that provides a balanced look at address, and also allows Ping to place a steel weight in the heel and tungsten in the toe to ensure stability and make it highly forgiving and accurate. Also, the Tyne 4 model features a "flow neck" hosel, and this promotes a strong-arc stroke rotation. Dual-Durometer Insert The front layer of Peba is now softer for precision on shorter putts, whereas the back layer is now firmer to ensure distance control. Shallow, Uniform Grooves Featuring shallower grooves that are uniform depth across the face combine with the dual-durometer insert, creating a soft feel and a consistent roll. Multi-Material Construction Ping has built these Clubs using different materials of varying densities. Different materials include 17-4 Stainless Steel, Tungsten and Aluminium. These materials combine to increase MOI and optimise the CG for more forgiveness and are applied to multiple head geometries with a variety of alignment options.
