Wilson PMP Raw

When Wilson changed its groove design, the differences were in the ten-thousandths of an inch. In practical terms the groove is now more square-like. It's legal, and like many in the wedge game, its sharper edges and steeper sides push spin rates closer to what they once were. The edges mean better grab, and the steeper sides channel debris for cleaner contact from the rough. The 11 laser-etched lines between each groove give partial shots more spin, and the raw finish of the 8620 carbon-steel head yields a softer feel.
