That is definitely a very nice buck. Like some have said, it's your buck do what you like. I personally like racks with character...the more the better. That's why I thought leave as is.
Il_BOW_MAN,
What if he had it when you shot it, but not after you found him?
That kind of goes back to what I just said. It gives the buck some or more character and like in your case, you have a great story to tell as to why it's missing. I doubt you get sick of telling that story...I wouldn't. It's a good one.
Or you could drill a little hole in the tine and then put a piece of rope around it and hang it from it's neck. Whitetail jewelry. LOL
Good hunting...
