I wouldn't be comfortable enough to even be in the tree at 30-35ft.
I start to hit a wall of comfort somewhere around 22-24ft for some reason (I know because I have a marked 30ft hoist rope.) I do get better as the season progresses and I climb trees day after day again.
Onemorning in Illinois I started climbing in the dark and when I hit the end of my 20ft hoist rope I locked it off amongst some good back cover and settled in waiting for first light.........when it got light enough to see that's when I relaized I own a 30ft hoist rope.[:-][]

Still I have no need or want to hunt that high even if it means an advantage.

I have heard a few times about guys using that strategy to hunt certain spots where deer can approach from the downwind side. They'll get way up in a tree very tight to the trail hoping their scent goes out way over the deer. Lone wolf's previous owner/founder Andre Dequisto (sp?) mentioned that in a video one time. Can't really argue with HIS success either.

Could be an effective strategy but I lack the spine for it.
