To really get a shot of something new you want to hand pick some fresh import however only a few people in this industry get to do that, you can also buy "un-open" bags of CH import, however people in Africa have always went through them, and importers go through them once they get here before re-bagging the animals by lot of 5 or 10.
Last option buying a dinker that someone that hand picked (can be anywhere between $100 to a few hundred $$$) so it really depends if you are much of a gambler you are and whether you are willing to lose a few hundreds for something that might be nothing more than a normal.
