600km loop out of Joburg - Where to go?

[iamgigglz]

Next weekend we're going into quarantine for two weeks before baby #2 arrives, so I want to do one last ride before all that happens.
I'm tired of Breedts, Canals etc for now and I did the Vaal & surrounds recently.

I was thinking Bronkhorstspruit, dirt to Loskop and then follow my nose in the general direction of Belfast/Dullstroom. Or slab it to Dullstroom and do that route back.
It's a route I've done a number of times before. Can I do better? What's out Standerton direction?
