Once again I need some advice

If we are going from Kruger to Hwange which route would you take? We will exit Kruger at Punda Marie.

Would you take the quickest route to Bulawayo and then to Hwange? Or would you cross into Botswana, drive via Francistown and cross the border at Pandamatenga? I am leaning towards going through Botswana.... There are some mixed reports about bribery and other problems with the police in Zimbabwe...
