Just wondering if anyone has any preference at the driving range regarding mat tees versus hitting from the grass. Who has more luck where, and why? Furthermore, which would you suggest hitting from if you were a golfer who used to have a swing but just hasn't been hitting the ball well at all lately?

Personally, like the grass because I can learn from the divots I take (or don't take!). It's easier to shank from the grass, though, which means more time is wasted trying to re-learn my swing. The mats are great for ball-contact, but they stop the club from coming down through the ball as much.

Is is just me, or does anyone else notice that time at the driving range doesn't hold a candle to actually going to the course to learn technique?
