RAH, my best buck stand is also no more than 10' off the ground... I can hunt the crap out of it and not disrupt the deer movement, but that is more attributed to my access in and out than it is anything else.
There is no question that being higher allows you to get away with more movement and scent, but it definitely isn't required to kill a mature buck regardless of score.
