When they mount the buck they cut the antlers off and work with the cape. I don' t see how it would look bad if you used another cape. The only thing would be if you used a small doe or something. It might look strange but then again, it might make your rack look HUGE.

I have a buddy who has a big rack from a few years ago and is looking around for a cape this year. If he does it I' ll post a pic of how it turned out.
