Actually, you might not need any clubs, especially being indoors.  The fitting is an educational piece/ question & answer where the Titleist representative will fit you based on how you answer a few questions.  This is a viable start in the ball fitting process though not hitting any balls.

Yeah but you may want to take some of your clubs to compare

Hi memphisunited,

Great question. You won't need to bring your clubs.  This is an education and selection event that will help narrow your options to a recommended and alternative Titleist golf ball. After the fitting we hope you'll head out to the course with an on course evaluation scorecard to fine tune your selection, and end up with the one golf ball that will help you shoot better scores. Have a great time at the event!

Went to the event today.  The rep was a nice guy and I'll be using the evaluation scorecard during my round tomorrow.  I have only used Pro V1s, so it will be nice to do a comparison with the Pro V1x.  Thanks.

Is there a schedule on where the Titleist Ball Fitting events are taking place?  I live in the Bay Area of Northern CA.
