I was fortunate enough to be the friend who got to join Tom Parker, the Grand Prize Winner, at the 2013 Oceanside Experience. Having been through a few fitting experiences at local courses, and being known for being frugal, this experience was, to say the least, an eye-opener.
I have played golf for over 45 years, and always felt that the golfer was 99% of the equation. After 5 hours with a professional like Robert Bunn, the confidence I have in my equipment makes all the difference, and helps me realize that properly fitted equipment plays a much larger part.
Looking forward, I would definitely invest in a Titleist Fitting Session before purchasing new clubs. Relatively speaking, it's not that expensive, and the confidence it builds is priceless. Oceanside may not be an option, but, Titleist has many Certified locations across the country.
Do yourself a favor and utilize Titleist's resources. They're second to none.
