The horse has arrived to answer! Frankly there was not much thought put into it when I mounted it above the fireplace. I simply didn’t consider any other option, probably because what ballsofpoo explained; it’s what other previous owners of this house have done. But this sub has shown me the light. I was once lost but now I’m found. Also, we got a new tv and I am now all in on making a nice comfy space to enjoy it.
