I've always wondered - with the bigger trophies - why not mount the head against the wall on a plane that runs from the throat to the top of the shoulders? The trophy would then look like a "low mount". For those with issues of wall space and trophies that "invade" into the room, this might be a solution. True the trophy wouldn't look like the currently accepted shoulder mount, but this perspective would display the boss of a buffalo to perfection! Afterall isn't that the reason why the trophy's been mounted - to display that boss, it's character and the sweep of the horns?
In order to avoid hitting my trophies with my head, they are mounted high on the wall to get them up and away. But the downside from this viewing angle are that the throat and necks are perfectly displayed while, for the most part, the horns aren't.
But, by using a "low mount" - meaning the trophy's head is down as if grazing - horns and bosses present themselves to best viewing effect, against a backdrop of a "teardrop" shaped mount that also emphasises the top of the neck with the mane or ruff. In this way the caping off of the skin would be inverted - leaving the mane/ruff untouched, with the cut extending along the underside of the neck. Once mounted, the trophy would be closer to the wall, lighter to mount, and, lessen "invading" a room. Other advantages would be savings in the size and weight of the finished trophy - which may have cost savings in packaging, freightage and maybe also taxidermy work.
Just my 2-cents worth.
