Wayne,
After using snuffers since the mid eighties I was gearing up for a moose hunt, but thought I would be better served with a two blade head, so I mounted several and just like you I get much better flight and accuracy with the snuffers.
Like Paul said maybe it's in our heads, but something like that I want in my head. Confidence
in your equipment is priceless, especially when dealing with game animals!
I hunted S Africa last June and my snuffers did just fine as usual. I got a complete passthrough on a 52in Kudu and all 3 blades still shaved hair! I say use the snuffers , stay away from shoulder blades and you will be just fine.
BTW, the vitals are much further forward on African game than on a Whitetail.
I will be hunting Elk in Nm with 2short in Sept,and I will be totting Snuffers, I hope this broadhead issue doesn't get out of hand.
Good Luck in Africa.
