I was so pumped about getting my new grips for my Eye2 (2 Ping grips golf pride tour velvet) and Titleist (2 golf pride tour velvet), I went to my local driving range to get them put on. I left very good instructions, I even put a rubberband around each club with the exact grip. Murphy's Law, the dumb idiot put a Ping Grip on a Titleist and put a Golf Pride on the Ping. The other 2 were done right. You'd think that with the actual name PING, I'd want the grip on my PING not my friggin' Titleist.
The moral of the story is: Learn how to do it on your own. If you don't do it yourself get someone you know well to do it. The funny thing is, I live next door to a former golf pro, but he left the business to sell real estate. I felt bad because he already reshafted my last driver.
