all my stands are 15 feet. i have a couple hang on stands with climbing sticks, i can get those up closer to 20 feet, but I have never noticed a real difference. trying to get by a deer's senses involves taking care of a whole combination of things, including scent control, camo, limiting your movement, etc. I think some guys get off on the 20 feet or higher thing because there is always someone out there looking for that one "magic trick" to getting deer every time. every little bit helps I'm sure, but I never worry about it. plenty of guys shoot lots of deer all the time sitting on a stump behind some bushes, so the difference between 15 feet and 20 feet I dont really believe makes that big of a difference. but everybody has their own thing.
