The reason I discourage Non-Competes is that the courts change the covenants so frequently, there’s no real way to have a solid template to develop one.

The ruled on August 7 that California employers cannot enforce agreements limiting competition by former employees, except within very narrow statutory exceptions.
If you really believe you need a Non-Compete Agreement for your employees, please consult your attorney. And read this excellent article from Cooley Godward & Kronish LLP.
