I used a Magnus I on my Kudu and Zephyr Sausquatch on Impala, Red Hartebeest, Zebra, and Nyala. My Eland I shot with a Doug Campbell damascus broadhead. The Eland was the only animal that I didnt shoot through or at least have the arrow hanging out the oppisite side of and that is because the arrow went into the offside shoulder. Paul Brunner recomends using the widest broadhead you can and he has spent more time in Africa than anyone I know. When I make it back I will be using 160 grain Snuffers and 4 blade Zephyrs. If an arrow makes it to the far side of the ribcage it has done all of the damage it is going to do. The trackers I saw at Vissers didn't even look for blood when tracking, they followed the hoofprints so I don't think that an exit hole is as important for them as it is for us. You are also hunting under controlled conditions as far as knowing the distance to the waterhole and with the concealment that the blinds afford there is no reason not to wait for a perfect shot. For me I will take maximum cut over penetration as long as the broadhead will make it to the far side ribs. Joseph
