I am sure that this has been brought up before, so I apologize in advance for the duplicity (just couldn't find an older post). I am considering upgrading to the 910 D2 driver. i have been to the range multiple times with it and am very comfortable with the performance. i ended up selecting the made for titleist blueboard shaft. i would like to know if there is enough of a performance difference between the m-f-t and the real thing to warrant the upcharge, and assuming there is, what would the difference be?
Thanks in advance for the help.
