Clayton - I have an almost identical set-up as you, including using center position in Nethawk's mount. I have 73 hrs (over 50 with this set-up) and it has done very severe service, including hauling firewood, (gravel, rocks & dirt out of a wet steep pit) & plowing snow. Mine is as quiet as a church mouse. No suggestions but I do not believe noise is caused by this set-up.
