For me, height is irrelevant. What's FAR more important to me, is the:
1. Elevation of the base of the tree in relation to the terrain I anticipate the deer to approach from.
2. The amount of cover that's in the tree, especially if from the deer's eye view, I will be skylighted.
3. Position of the tree in relation to the approach route the deer will take, i.e., I don't want to be on the OUTSIDE edge of a bend in the trail, because they will be looking straight at me when they make the turn.
4. For gun hunting, I will go as high as conditions dictate. For ARCHERY hunting I don't like getting higher than 15' to 18', because anything higher makes for some REALLY steep kill zone angles, with much less margin of error due to the decreased size of the kill zone from above. I am of the opinion that a lot of deer are wounded and not recovered because of "nose bleed" shots with bows. I'm not saying that you can't kill them from the cheap seats...they will die every bit as much as from a lower angle, IF you can put the arrow where it has to be...but it does decrease target size considerably.
