Hi,
I recently bought a 910D3 with the Aldila RIP shaft stiff flex at my local golf shop.
When I was buying it they did not have the one I wanted in stock so we swapped shafts between drivers so they wouldn't have to special order the club for me.
Should we have changed the weight that is in the head also? The original shaft was the Kai'li.
thank you.
Curt
