I agree that face is going to dictate initial direction, however, since an angled hinge has more of a no roll feel, the face will have a tendency to be more open at seperation than a horizontal hinge, which has a more rapidly closing clubface. You can adjust for this, by setting up with a more closed clubface at setup.

However, no matter how you swing the face and it's relation to path will dictate ball flight.
