I was amazed on ROAR 1 how little jet lag I had when we got to Capetown. One thing that may have helped: we had a long layover in Zurich (12 hours), so we got a day room at an airport hotel. I took a shower, slept about 6 hours, walked around a little and went back to the airport for the flight to JNB (which was an overnight flight). We slept again on the way to JNB, transferred and flew to Capetown and arrived feeling great. The Europe to South Africa flight is fairly easy because you don't change more than one or two time zones. It's the flight from the US to Europe that's the jet lag flight.
