Important though, you will need to know how to set up anchors at the top (same goes for Roche Rock). Also, it is much easier to set up belays such that you belay from above, as getting a bottom belay set up just right takes quite a bit of skill, so you need to know how to belay a climber below you and what it feels like when they fall (this is much more of a skill than holding a top roper on a bottom belay, if possible try to practice it under supervision at your local wall).
