I recently bought a 910D3(right before the 913's came out) and I love the look of it but I don't know about the shaft or the setting thing. I have owned and used my 975D driver since the first day the proshop was literally putting them on the shelf. I can't say enough great things about them.
That being said, since it is winter in illinois, I've been to the range with this driver and it seems it will take a lot to get it figured out. Being hard headed and very old school i am getting frustrated. Does anyone have any knowledge for me that might get me back on track. I think i need to keep hitting balls and it will get figured out but any thoughts would be great. Thanks and God Bless!
