Mizuno

St-Max 230

• This oversized entry stretches to the limits of the rules that govern high stability.
• Carbon composite swaths in the crown and sole save weight (54 grams) that’s pushed deep within the frame to create more forgiveness.
• A channel cut in the sole extends heel to toe to increase flexing in the face.
• The channel includes a five-gram steel weight to further lower the centre of gravity.
• Top 5 in Forgiveness, low-handicaps.
• 9.5, 10.5, 12 degrees (eight-way adjustable hosel).

ST-G

• Its compact shape (440 cubic centimetres) means this model targets ball-strikers looking for reduced spin and adjustability options.
• Two tracks in the sole feature seven-gram weights for changing the head from extremely low spin (both weights in the front) to maximum stability (both weights all the way back). It also can be adjusted to favour a draw or fade.
• The channel cut into the sole maximises face flex.
• A beta-rich-titanium alloy makes the face lighter, stronger and faster-flexing.
• 9.5, 10.5 degrees (adjustable hosel).

ST-X 230

• This head uses a 14-gram sole weight in the heel to provide draw bias and make it easier to manipulate the head during the swing.
• That weight also rests deep in the sole to boost stability on off-centre hits.
• High-strength titanium in the face creates more ball speed on mis-hits.
• Speed also comes from a channel in the sole that improves deflection, particularly on lower impacts.
• A three-gram steel bar within the channel lowers the centre of gravity.
• 9.5, 10.5, 12 degrees (adjustable hosel).

ST-Z 230

• Similar in profile to the ST-X, this model features weighting that is more neutral to emphasise forgiveness across the face.
• A 14-gram weight deep in the centre creates significant stability compared to the ST-G.
• The deep centre of gravity yields a higher launch.
• More speed comes from the channel in the front of the sole, which increases face flex, especially low on the face.
• A steel weight located in the channel further lowers the centre of gravity to reduce spin.
• 9.5, 10.5 degrees (adjustable hosel).
