I'm right there with you. I just started playing after 8 years, walked to a golf shop where they claimed if I were to invest on new equipment, driver would have to be at the top of my list. So, I got myself a new Callaway Diablo -driver, since I was never extremely consistent, nor confident with my old driver. Diablo worked fine for a while, and true, mis-hits don't cost me as much as they did before, but recently I've found the big head hard to accelrate. I'm sure I'll get there, but for now whenever I have to hit a narrow fairway, I'll go for my 2- or 3-iron.
Overall, my swing feels better than it did 8 years ago, but swinging the driver feels awkward and my confidence-level with the driver is nowhere near where it should be.
