In reply to RedEd:
climbing.co.za is the place to go to ask for route suggestions and company to climb those with. The SA climbing community is very tightly knit and climbing.co.za's where they'll hang out.
It's a little less rowdy than UKC, though, and, consequently, a little less entertaining to lurk in. Still, a grand forum non the less.
EDIT: If you want the true adventure, climb Bombay Duck on the lower tiers on your way up, then walk up to the ledge and climb Jacob's. Then talk your way into an abseil down the long commercial static lines (if they're still there and still amenable to charismatic climbers) and walk the rest of the way back down to the lower cable station. That'll easily give you the two must-climb classics in one day. (They're both graded SA 17 if I remember correctly but, honestly, they're such great routes you should find a guide to lead them and climb them anyway if that seems steep for pure trad., to you.) These two are entrenched in my "greatest routes of all time" list.
