noob problem..

[GuyClinch]

I got to say my forehand is bugging me. I want to hit heavy ball with lots of topspin. But whenever I try to hit harder and add more topspin I open up my racquet face. This doesn't happen with my one handed backhand at all BTW...

Ask a tennis coach to take a look at your forehand and tell you what you're doing wrong. That way you'll know what yuo're doing wrong and need to work on.
Maybe start with some mini-tennis. Try to get the feel for those topspin balls. And then gradually increase the speed and the intensity level from the back of the court. Make sure you don't force anything and don't muscle your way true the ball when you're trying to hit harder. Stay loose.

finish with the racquet face perpendicular to the ground, ''square''.

Not really a noob problem as heavy balls are a mystery to some experienced players. If you're having a problem with an open racquet face, consider experimenting with a new grip (semi-western maybe?). You'd be able to essentially retain your form without having to worry about an open face.
