Yes, that's about what I've observed.
Guys like Roddick still have the toss out front, but not as far out front, because the racket is moving more across than directly into the ball. As you've noticed, if you put it too out in front, it is going to be hard to spin. But if you put it directly over your head, you're not going to be maximizing pace and your body won't be in the proper position to really let it rip.
