I used a MR Bighorn on my Aoudad hunt and have used it on several day hunts. With the 'wing' on the back, I can lay my rifle on the pack and snug up my rifle quite easily for all day carrying.

The Eberlestock would be a good choice for this type of hunt and my partner used that on the same hunt.

You wont be packing much meat (if any) and the horns/cape are the only real concern. Man oh man I want to go back and shoot another one of them critters sometime soon!
