News & Review
GolfWRX TENSEI 1K Pro Blue Review: Fri, Oct 20, 2023 — "Out on the course, the TENSEI 1K Pro Blue is smooth and responsive like you would expect from any Mitsubishi shaft...The Blue has a smooth feeling to it that loads easily and you can really feel the shaft build up some energy as you start the downswing."
