The thousand dollars off is really pretty inconsequential in the big picture. But it is a really decent price to hunt leopard on a wild area if you add days and buffalo. The cost of PG and bait is going to add up but that is a lot of hunting in a wild area at a good price.
I never did see a percent success number. But if I could go I'd take my chances just to go to the area.
A MUST do in my mind for that area is Nyala... I have been around some Nyala enough to know when I take one, I want it to be a great one

Two places i have seen that type of Nyala are Crooks Corner and Bietbridge East.... all that general same region.
