Weight Adjustment Guidelines (Useful reference)
Here are some useful conversions that will help you when swing-weighting your clubs:
Note: A 1 point increase in swing-weight points would be the equivalent of going from D1 to D2, while a 1 point decrease in swing-weight points would be the equivalent of going from D2-D1.
|Condition||Change in Swing-weight points (SW)|
|Cutting 1/2" off grip end of shaft||3 SW decrease|
|Adding 2 grams to clubhead||1 SW increase|
|Adding 5 grams to grip end of shaft||1 SW decrease|
|3 layers of masking buildup tape under grip||1 SW (ex: 90 g shaft=1 SW more than 80 g shaft)|
|Flattening lie angle 4 degrees||1 SW increase|
|Shaft weight difference of 9 grams||1 SW decrease|
|4.5 inches of normal 1/2 inch wide lead tape||1 SW point or 2 grams|
|3.15 inches of "high density" 1/2 inch wide lead tape||1 SW point or 2 grams|
This table represents the general guidelines that I have followed for several years, but they aren't perfect. Always be sure to measure!
