As stated by many below, the Shaft is the Engine of the club, so a properly fitted shaft makes a great deal of difference.
When I Started this company (AccuFLEX) after being in the custom club business for 10 years, my goal was to create "A Golf Shaft to Fit Every Swing" instead of us golfers settling for what came in our clubs.
The Shaft business has really been given alot more notice over the last couple of years, and many advancements have been made.
We enjoy this segement of the Golf Business World, it is very exciting and we find more and more veryday, that we can improve a golfer's clubs by fitting them into the proper shaft(s)
If you ever need any help or suggestion, let me know.
Thanks for the Space.
Take Care,
Jody
