I've hunted Matetsi a couple of times, and have always found Unit 2 to be great for plainsgame. Last year on an elephant leopard hunt I managed to get - in addition to the elephant (55lbs -- 52 lbs) and leopard - I picked up three impala (bait), a kudu, bushbuck, hyena, waterbuck, eland, and baboon. In the past, I've taken most of these plus cape buffalo, sable and giraffe in Matetsi. Plainsgame is reasonably abundant, and at least where I've hunted, the facilities are fine. i don't think you can go wrong there. No fences and lots of land.
I've hunted with PH Dean Stobbs (dean_stobbs@hotmail.com) every time I've been in Zim, and I'm making him come with me to Zambia when I go there.
