Generally more control with a smaller head because weight directly behind the ball, but with the advent of incredible Poly Strings it doesn't matter that much anymore. I used to be a small head only player, 6.0, but now use a 100 Bab PD, only difference is more power and more forgiving, small racquets will go the way of the Do-Do with Poly, although I love to break out my PS85 and 90 and nothing beats that feel, and nothing better for practice.
