400 Spectrum FX-4 | Harper Thompson 2025 Signature Series

The Acid Rain Broodmother looms over the cities and skylines as her colossal legs stride effortlessly over buildings. Clouds of searing rain gather at her command, melting stone and steel beneath her venomous storm.

Harper picked the FX-4 Fairway Driver in 400 Spectrum. The FX-4 is a fast, stable to slightly understable fairway driver. With a wider rim than our F Series, it carries more speed and pushes further down the fairway. In flight, it will have neutral to slightly understable characteristics depending on your arm speed. Power players will see some movement to the right (right-handed backhand), while lower arm speeds will give a straight ride with a mild finish.
