Nilgai is great table fare, cooked right it's hard to beat.

And they're rather large animals, lots of meat. Be sure the guide has plenty of ice and gets them skinned out and on ice ASAP, as it tends to be hot where they grow...

I think the bottom line is what you're comfortable with and what your guide is comfortable with. I'm going to go with the flow and not go trying to prove a point. He likes big stuff, I'll shoot big stuff. Not a problem.
