Titleist Pro V1

What is the difference in the spin rate off a driver with the new Pro V1 compared to the previous Pro V1. Is there a significant difference and will I have to change my driver settings to compensate for the different spin rate.

Thank you

The Prov1 spins a lot more off the tee than the Prov1x. Look at http://www.titleist.com/golf-ball-fitting/    

That will give you education on the balls. As the Prov1 spins more, the Prov1x gives you more distance.
