To the OP, if he’s still around, those are two mature buffalo but NOT old buffalo. When you see an old buffalo bull you will know it! Not much hair, big dewlap, worn tips and what birders call giz. You just know it when you see it. Both bulls are going to be exceptional especially the bottom one. He has better drops than the top bull. If my PH says shoot I shoot and if he says we can do better I hold fire. Plus by the time you go the bulls will have more age on them depending on when your safari takes place.
For some reason buffalo and wildebeest seem to bring out a lot of opinions on this site which I really like.
@gizmo, you really pissed in some Cheerios on this one!! I love the back and forth.
Of course all of the above is opinion only.
