Hi,
I recently purchased a 913 D2 driver. I am wondering about the interchangeable head weights. What 'weight' is the standard weight that is included with the driver (believe it is is the 'red dot' one). What are the other different 'weights' available.
What are main reasons for changing the weights ...either lighter or heavier ? ... just feel ? making head lighter to possibly increase swing speed ? ... possible changing centre of gravity ?
Thanks,
Troy R.
