I custom ordered 9.5* 913D2 driver with a RIP alpha 80 X shaft (std length) with a tour velvet cord grip. It has the green 7G weight in it from the factory.
I want to put in my old shaft from my 910 driver a Motore Speeder 7.2 X flex (76G) with a golf pride z-cord grip but I want to keep the swing weight the same as the set up with the rip alpha 80.
What weight should be in the bottom of the club, I'm sure i need a heavier weight than the green 7 gram weight. Will the red 9G weight get me back to the same swing weight?
