The animals most important are the Giraffe and the Blue and Back wildebeests. Would it be better to focus on these animals and hunt the others as targets of opportunity?
Ok, just looked at where you are going. (You have read my hunt report on the Outfitter.)
If nothing much has changed since I was there two years ago, and nothing much should have, here is my opinion from being on the ground.
With some luck and straight shooting and the great support team that is at your Outfitter you could get two out of three of your list the first day. Giraffe and Blue Wildebeest. With some more luck you can find that Black Wildebeest the same day.
Gemsbok, Steenbok, Impala, Burchell Zebra are all there in high to good numbers.
The one you could be pickiest on is the Gemsbok.
There are lots of Eland and I saw Kudu bulls every day.
If you see a good Kudu, take it when Diana smiles on you.
That should take care of most of the top of your list.
Have fun.
