Thank you very much for all the comments... All of the species seem to me very unique in their own way to hunt.
As for plains game, I would go with a old, greater Kudu bull on spot and stalk... Very challenging.
As for Big Five, I would say Leopard... For the simple reason, its one hell of a challenge. And getting a big Tom ALWAYS gets your heart going.
Few hunts get he adrenaline pumping as much as that of sitting in a leopard blind and hearing that cat come in... Will it get into the tree...? Is it the same Tom we saw on the trailcam pics...? Are we going to be quiet enough...? Will we get a shot???
And then of course there is Cape Buff in true free range country... Having spent days in search of or on fresh tracks and finally getting close... Are they going to see us...? Is the wind going to change...? Is there a big bull in there...? If so - are we going to get a shot at him?
Elephant hunting is high on my list and in August of this year I will at least experience the hunt - and depending how the tracking goes hopefully we will at least have a few close-quarters elephant encounters.
A C.A.R. safari has been at the very top of my wish list for a decade and I have a hunt organized for 2015. Still a whole away, might take the wife and girls along, and a mate of mine might come along formal hunt as well. Eland, bongo, giant forest hog and the endemic plains game.
Somewhere down the line we're gonna' need an East African hunt for Lesser Kudu, the gazelles and other local species. Maybe a lion somewhere in there? Lot of water has got to pass under this bridge for that to happen!
Lying prone in the long grass after a perfect stalk. Invisible to the game around you. Watching a lead Springbok buck graze across your front in the lead of his harem. Judging the curl and backward sweep of his horns. Correctly estimating the range and releasing a .308W 165 Woodleigh PPSN across 200 paces of grassveldt to watch it connect at the junction of neck, spine and shoulder and then realising he has dropped from sight. DRT.
