The Titleist driver shaft matrix has tens of shaft options with hundreds of choices when including all the flex options for each shaft. Even in the category of higher launch/lower spin shafts, there are too many to suggest. A good fitter is like a good mechanic - that person can look at your current combination and quickly narrow down the choices to 3-4 and then find the best choice based on your swing.

Agree, see a Titleist certified fitter...
