I used Mckenzie MV100 ear forms for a deermount. 2 months later I decided to bring this same mount to a state competition, mainly for the idea of having deer scored for customer use. As a taxidermist doing customer work i would like to know want I can do do improve my work for clients. During my critique, I was told my mount was a complete train wreck. My ear forms were completely wrong. Funny their are wrong when I used the MV100 and a photo of a live deer at a sportsman show. to put the mount together. As a machinist quality inspector, inspecting boeing aircraft parts and measuring. I measured everything to as close as I could. I will no longer bring any mount to a competition, as have several others that have since stopped being part a state association.
