Remember, this is just a ball park figure for normal most case.

Some shaft have tip or butt weight will not be applied on this rule.

1/2" = 3 swing weight points

2 gr club head weight = 1 swing weight point

5 gr grip = 1 swing weight point

9 gr shaft weight differences = 1 swing weight point

4* flatter lie = increase 1 swing weight point
