sorry Kip, for seeing this only after you have returned from africa- but thought i might just answetr anyway- for the benefit of others.
i assumne you are hunting in winter( hunting is available all year round in africa).
but nothing beats the asat leafy suits. i am originally from natal, in S.A. and i took calgary chef back there hunting- check out his thread "40 days in africa" (i think!!)
look at all the natural colours on the game there, and believe me they hide pretty well!!- look at the dirt and the tree trunks- thats where you are gonna be hiding. besides all the acacias etc lose their leaves- not too much bright green moss and green oak leaves around in the semi-arid bushveldt.the asat is on a mesh backing wich helps with ventilation too - the asat is the best- without a doubt!!- personal experience.
