In reply to purplemonkeyelephant:
There are difficulty ratings for VF routes. So you start with easier ones, work to harder as you feel comfortable, get better at techniques.
Note that if using a normal VF kit ... and you also fall -- most likely the lanyard connection will prevent you from dying. But you can easily
still get _hurt_, perhaps injured seriously. Because the VF kit and the fixed cable will still allow you to fall a significant distance. And there are things on the routes which will hurt you badly if you hit them in a fall: notably the protruding steel cable anchor posts, but also rock horns, ledges.
Belay?
Like with many other kinds of climbing, if some member of your party does not want the risk of a fall, you can belay them with a rope (if you have and know how to reliably effectively use a belay device or other belay method)./
When Sharon comes with me on more difficult VF routes, I often bring a 16 meter rope and belay device.
