Great Bull congrats! I really don't like a straight mount. Give them a turn and it adds so much more life. If your talking about a McKenzie(form company) semi sneak offset shoulder mount they are turned very little so you kind of get the best of both worlds. If you are going to hang him high you might look at McKenzie's antler clearance form, (but we like to pick the nose up some on our mounts, on that form. I don't like the nose down, but they do that for antler clearance for really large bulls.)
With this said, depends a lot on how much cape you left, the offset does take more skin.
Hope this helps. Get what you want though, so you will be happy with him. Left or right turn depends on where you will be hanging him and where you will be viewing him from.
