I have made 8 trips to Zimbabwe with probably 24 weeks in the field total. I personally have carried doubles on 3 trips. The total number I have SEEN while hunting there not including my own is the sum total of 3. I have hunted dangerous game on 7 of the 8 safaris all over Zimbabwe. Doubles have not been very common in my experience, but that is only in Zimbabwe which is the only country I've hunted.
