Hmmm.... It seems that the majority of us have gone against the new conventional wisdom. I am surprised to hear that most of us are partial to the lower ball flight. This is very interesting.
I have recently switched to a 8.5* driver head and I am loving it. I was hitting some piercing bombs yesterday. I tend to find more fairways when I am hitting the ball a little lower. It is harder for me to clear some of the corners at my club, but I have learned to adjust my setup to gain more launch.
Keep the replies coming!
