Yes, this is one of those questions.
What size rifle do you need for Kudu ?
I'm in the camp that believes a lot of hunters go to Africa overgunned. I used a 9.3x62 on my last hunt on the recommendation of my PH (I always listen to my PH) as Eland was at the top of my list.
I was also after Kudu having missed out on successfully hunting one fair chase during my first paid safari. I got three, one 50" and two male cull animals with the 9.3x62 and 286 woodleighs. On that limited number and various conversations I formed the opinion that Kudu were not that tough.
I'm taking a 7x57 with 154 Interlocks back for a larger Kudu on my next hunt. A .308W with 150/165's would IMO be even more of a good thing. I will even go so far and say a .243W with 100's with careful shot placement would be enough if prepared not to 'blaze away' at the first sight of the quarry.
What would you use, just for Kudu ?
