If one were to upgrade clubs every year they are either rich, or lucky perhaps ...but anyway, I know manufactures like to offer the best product they can and the OEM golf world is very competitive. I am Titleist all the way, I've occasionally tried other clubs but I always come back to Titleist.

What  are the gains in buying the AP2 712's vs. the 710 model.  What difference would a 3 HDCP see?   I upgrade clubs every 3-4 years mostly due to wear or I have clubs re-shafted or re-grooved.
