I have a 910 D3 with a diamana ahina 72 gram stiff flex and I its a little whippy for my swing speed 110.
I have a ahina shaft that is an x flex without the sure fit hosel that was removed from someone elses 910 D3 and given to me.
How can I switch out these two shafts? Is this easy to do or will I mess up my club? Thanks for any help you can give me.
