Yes, it's a grip-technique question.
When you tee off with a driver, where do you place your thumb? Is it in the center of the disc or on the edge?
I haven't been playing long, only a couple months or so. Until recently I was using a power grip where my thumb would be right on the edge of the disc. I threw okay with this grip, but made a lot of inadvertent hyzer shots. Being a lefty, I would have to aim to the extreme left of the pin in order to compensate for the tremendous arc that was my usual flight path. For the life of me, I couldn't figure out how to throw a long, flat, straight laser shot like I'd seen so many of the experienced guys throw.
The other day I was practicing drives on Cliff Drive #13 when I decided to try moving my thumb to the center of the disc to see if it made any difference. Damn! I made the longest, straightest throw I could have ever imagined. I made a few more throws to make sure it wasn't a fluke, and they all stayed straight and long. Eureka! Finally, I've discovered how to throw a driver far and straight.
So, I was curious-- where is your thumb when you drive? No place nasty, I hope!
