Hi Britt.  I am only asking for your opinion on this subject.  If I can buy 10 more yards with my driver it will be well worth it.  I am 78 years old and my swing speed is 78-80 mph.  My best hits will go 200 yards and have a slight draw.  The equipment I am using is a Titleist driver head model 910 D2 with a 10.5 degree loft.  The shaft is a Grafalloy Pro Launch Axis regular flex weighing 60 grams.  I realize these are now outdated, but will newer technology help?  Also, I need to see a fitter I can trust as I have been to one in the past that I didn’t think was very knowledgeable.  Would appreciate any suggestions.
