Cut Spin

This example shows the negative effect of too much cut spin on the performance of the golf ball. The cut spin number (+43) turns RED to highlight more than an acceptable amount of cut spin imparted on the ball at impact.

This cut spin caused the ball to skid for 2.13 inches and the initial ball roll was negative (-33.29 rpm). The launch angle in this putt was high (2.69 degrees) and the putt was 4.62" right of the centre of the hole at 8ft all off which indicates that the putter face was probably open at impact. A combination of the putter path, face angle and the model of putter all contributed towards the high amount of cut spin.

As a result, it has taken considerably longer (28") to reach the point of 'True Roll'.

Common causes of too much cut spin

• an outside to inside putting stroke
• an open putter face at impact
• striking the putt out of the ‘heel’
• putter with lie angle too low (heel high)
