The Aeropro Drive (which Nadal uses) is a great control racquet because it allows for a lot of topspin and gives you the ability to hit harder without worrying about breaking the back fence.

Before you try any other racquets though, I would suggest you try changing the tension on your strings to more control-oriented settings.

1. Try increasing the tension in your strings by 3-5 pounds.
2. Try using more control oriented strings (e.g. Babolat Xcel premium)

I have a Pure Drive as well and I string it with Xcel premium mains and Hurricane pro crosses for a combination of power, comfort and control. I always string my racquets at 60 pounds, because I'm a big guy who can generate enough power from my swing. If you feel you generate more power with your swing than you need to, try stringing at 60+ pounds (upto 62 pounds per Babolat's maximum tension recommendation).
