can you please tell me again what you want to know ...?
Having never weighed stag heads, I'm curious as to what 4, 5, 6, ... 12 kg racks look like. Seems those of us on this side of the pond don't base quality on a single index. We usually relate to things like point count, spread, circumferences, height, etc or some combination of those. Some even suggest we apply a water displacement method to assess volume.
In my mind the above would be a fine trophy, but I have no idea what it's mass might be.
