I haven't been to Shongweni in ages... but as far as I know, the main security problems are fairly recent which is why it's not mentioned in Rogers book. It is also getting pretty expensive to get in there as far as I remember. I think Kloof gorge is a better bet, Rumdoodle is a popular intermediate place to climb. Otherwise, you can come up to Howick area and climb at Umgeni Valley and Howick Falls, both are incredible venues! Let me know if you're looking for a climbing partner, there are quite a few climbers up here that you can fit in with. There are normally a bunch of Durban climbers at Umgeni over the weekend so ideally you should try get in contact with them, hopefully they can add to this post as well.
