Nice idea Jaco. The problem I see, with only 4-8 areas, would be that there won't be enough areas to meet the demand. Like you mentioned in a previous post, if we try and get away from the "3-day hunt" scenario, we will have too many hunters wanting to hunt a lion, with not enough areas to house them on over let's say a 10 day hunt. This is accepting that only 1 hunter will occupy the area for the hunt. I think there is certainly substance to that suggestion.
Alternatively, we can just say, Screw it, those are the 4-8 accredited areas, so many "hunting days" are available per year, first come first serve, but like you say, then I can see a formidable price increase.
A wilding period of 6 months seems fair, but who will carry the losses for the plains game animals hunted by these cats during those 6 months? Maybe better use can be put to the "Red-Line" meat to feed these cats? Just an idea.
