World Of Weights Fits Mizuno ST-X Driver & Fairway Wood Weights

World of Weights NON-OEM – Mizuno (ST-X230, ST-X Pltnm, ST-Z 230 Models) Driver weights are available in 3g, 5g, 7g, 9g and 11g. Adjusting the weight can help optimise launch and spin on your current driver. Placing a heavier weight toward the back promotes higher launch and increased spin and more forgiveness, while changing it to a lighter weight lowers launch, reduces spin, and produces a more penetrating ball flight.
