I want to expect challenging hunting, busted stalks, physical effort, and pride in a well-placed, hard-earned shot.
If you do not collect all the animals from the list, would you still consider a hunt to be successful?
General plains game safari in Namibia and South Africa, 5 to 7 animals, is 99-100% successful.
The success (or challenge) will largely depend on your skill to shoot.
Which means, standing from stick up to 200 meters.
It is 99% that PH will bring you to shooting position.
I have witnessed a group of less skilled hunters having about 20% of wounded and lost rate. (In Namibia). and trophy fees paid for. (the total value lost was more than 10k)
Shooting skill, in my opinion is the main thing. For such groop, the shooting was challenge.
That is also in my opinion an industry taboo: hunters will not brag about it, outfitters and booking agents will not advertise this.
(You know: our last group had loss rate of 20% but you do not worry, just come over, book and hunt with us, you will be better for sure, lets hope for the best...

)
But if and when you know how to shoot, there are still hard hunts, not always successful, and not guaranteed. Bongo, Leopard, mountain nyala.
Aardvark, aardwolf, serval maybe, rarely hunted, rarely reported on the forum.
Cheetah, not territorial, doesnt come on bait, hard to plan, hard to hunt for that reason.
Some of them will be one animal safari. Either you get it, or not.
Baboon is my huckleberry.
Baboon was never my priority, but I always wanted to take one.
On each consecutive safari I had other priorities, but last day or two I would try for baboon. And failed.
Safari number 4 I missed. In 4 safaris I had enough challenges with baboons.
I got baboon on safari no. 5.
I would say this:
Go to South Africa. Enjoy. You want to make "hard hunt", for second safari choose some species known to be difficult.
I have been 3 times on Plains game hunt, and 2 times on DG hunt. Of those: 4 times in Namibia, and once in Zimbabwe.
In Namibia I had busted stalks on various PG, but than we tried again next day. (mixed type of hunts fenced and unfenced) but the plains game was in abundance, everywhere.
In Zim, I had busted stalks, but hard to get a second chance on same species, due to terrain and animals being spread around and spooky. You bust a stalk once, it is a question if you will see the same species again.
So the next question is also are you flexible?
If not getting a kudu, would you be happy with something else like zebra?
