If your taxi will let you take the horns off your buck and put them on several different forms he has in stock that will give you and idea of how they will look(without the tanned skin on the form). If he will let you take it home to see how it looks on the wall even better. I am a fan of wall pedestal mounts also as I have quite a few of them. A free standing pedestal is great also. If you know and trust your taxi as his opinion on how he would mount the buck. I have done that on several mounts and they all turned out great.
Great deer. I always mount how they looked when I shot them. Just helps preserve the memory. If I ever get a 155" + I'll do a wall pedestal no matter what. It's your money get what you think looks best and will look best on the wall.
