My buddy and I have alot of fixed lock on stands ( 18 or 19 between us plus we each have a climber). we have them at different heights, depending on the situation. We usually try and stay between 20-25 ft, but some places we have to go lower. As a matter of fact, I shot my biggest buck from a stand that we hunt every year that is a the corner of the woods, and the shots are usually out in the open field. That stand is only about 13 ft. up because of the canopy. we have had lots of deer around us there and have never been busted. So basically all different heights. We are both scent control freaks, plus on top of that we both use Scentblocker suits so we are pretty confident there. Sometimes the situation dictates the height.
