The secret I think is to use large diameter trees. I've been 16-18 ft on the sides of monsters, with no other cover and the deer have been clueless.
Chain extensions, the inability to hug the tree when putting in steps/hang the stand (man it's fun trying to get the chain around, what with the extension and weight), it's kinda scary and weird, but it seems to make a difference.
Works way better when you have a helper on large single trunk trees.
Still hunt "skinny" trees. As low as 6 ft (killed deer too) and as high as 28.
For trad stuff I like 17-20 ft. But that's just me. 20 and up with wheels.
If cover is OK, I don't think stands under 10 ft to be bad either. You gotta be super careful though. The higher you go the more you can get by with.
