My climbing sticks get me about 15 up, and that' s worked well for me.
I' d go a few feet higher, but another stick would be just too much to carry.

I' ve only been winded twice, that I know of, and both times I was on the ground and the deer approached from downwind (he must have missed the memo), but still didn' t bust me until they were within 10 yards.

Scent is a big deal, but I wouldn' t sweat it. (hee hee)
Just go 15-20 feet up, depending on what the foliage allows, and get comfy.
