what is the swing weight of a 913 d3 9.5* driver with the stiff flex diamana 72 + shaft at 45 in length. mine came with the red dot weight .
D4 maybe. I have the same shaft in 910 D2 and it comes in at D4.
The red dot indicates a 9g bezel weight. There are 5 bezel weight options to help adjust swing weight (4g-white, 7g-green, 9g-red, 11g-blue, 14g-black).
