You are much safer with the torsion springs.
I manufacture the extension springs for several Canadian door manufactures. Last year I made over 50,000 of them. I personally have the extension springs on my doors. (with the saftey cable running through the middle) There is no way anyone should take a chance without the saftey cables. You should see what happens when one of these things breaks. It can damage the car, but imagine if it hits one of your family. Everyone should check their doors.
The installers only rescently started installing saftey cables.
