I think you should go for more than just leopard.
In 2011 I went for a "big 4" safari in Zim. I shot elephant, buffalo, lion, hippo (for bait), zebra, and some impala (for bait). Never got a shot at a leopard.
While driving around checking baits for leopard, you might cross some buffalo tracks worth following or, as we did, blunder into a bull elephant track good enough to follow.
Sadly, it's almost imporssible for Americans to import lion or elephant since then but you get the idea.
Some of the Namibia hunts have higher success with leopard but that's about the only game you can hunt except warthog for bait.
