Hey everyone, I am going to upgrade my driver setup with the new D3 and have tested the different shaft options. I like the stock version in stiff, but still think that the white board upgrade shaft is better. I have ball speed about 115 and club speed 105-110 but need to lower my launch from 15 or 16 to about 12. The 8.5 D3 with stock diamana ahina stiff did this without reducing spin rate, so I was wondering if anyone has the white board 73 or 83 on their new driver and can tell me its worth $200 extra?
