That's how I play!! I've been playing just under 2 years, had no lessons, and have never had a backswing, yet driver further than most of my playing partners. It also helps me draw the ball, as its like a baseball swing, flat and curved. If I were you, I would try it for a month or two, not just on the range or for one round. Its something you need to learn and get used too, but for me its a natural way to swing. I know that if i try to get a full swing i slice the ball badly!
