Product Details Slightly open at address, with powerful pear shaped profile and thumping feedback, the MP-630 FAST TRACK inspires imagination from the tee. While designed to suit the eye of stronger players, the shallower design and 445cc size will attract a broad range of abilities. Fiery ball speeds ignited by a HOT METAL Ti9 face are converted into optimized yardage using Mizuno’s FAST TRACK adjustable weight tracks. Two 8 gram sliding weights can be quickly re-located in 10 different points, creating a total of 45 finely tuned flight patterns. With weights set closer to the face, spin rates can be reduced for faster ball speeds, with a drop of around 400rpm achievable.The ingenious system can also be quickly adjusted to create both a draw and fade bias. Weights set towards the toe positions, encourage the clubface to lag for a left to right flight. Conversely, weights moved into the heel allow the clubface to rotate for a right to left shape.Tour Ready ProfileModern 445cc pear shape with open face.FAST TRACK 45Increased range of settings to fine tune flight characteristics.HOT METAL Ti 9 FACEMaximum ball speed and increased COR AREA.CORTECH Face designMulti thickness to enhance off centre strikes.Internal Rib StructureFrequency tuned for enhanced feedbackNote: FAST TRACK is a fine tuning device, not a fault correction system.SpecificationsLoft Lie Hand Swing Length Head 8.5 58 RH D3-D5 45" 445cc 9.5 58 RH D3-D5 45" 445cc 10.5 58 RH D3-D5 45" 445cc Shaft OptionMitsubishi Rayon/Mizuno Fubuki in Regular & Stiff flex.
