Zimbabwe. Bubye Valley Conservancy, Save Valley Conservancy, or Nuanetsi or several places on the Zambezi valley.

Book with a Zim outfitter and Zim PH. Shaun Buffee, John Sharp, Pete Fick are all very good on the BVC. Mokore is great in the Save. Lindon Stanton is a very good choice for leopard. Louis Mueller with Pro Safaris and CM Safaris are two more good people to talk to.

The bigger cats will come from the lowveld.

A 300 H&H would be great for everything you listed.
