hi I was wondering what swing weights my driver and metals are:

driver: 913 D2 8.5 degree with a 9g bezel weight

            shaft is aldila rip phenom 60g

            grip standard titleist

3 metal: 913 Fd 13.5 degree with 11g bezel weight

              shaft is aldila rip phenom 60g

              grip standad titleist

5 metal: 913 F 17 degree with a 9g bezel weight

              shaft is aldila rip phenom 60g

              grip standard titleist

I have heard that it makes a difference to ball flight and spin if so what would getting lighter/ heavier swingweight do

any help would be great thanks
