In my case it has been word of mouth. My brother set up my first hunt with Mark Kyriacou in Botswana. I have returned to Botswana 3 times and also hunted on Clive Eaton's ranch, Clive and Mark cooperate, and Clive was my brother's PH. Now that the Delta is closing I have decided to try Zim. I booked with African Silwane Hunters on Clive's reccommendation for 2011. My theory, listen to those who you trust. How do you make your choice?
