I learned a few years ago that if your perfectly comfortable, having your feet at that 20 foot line helps a lot as far a disguising your movement from deer. It also helps to get your stink above the deer when they are in close. Here in PA, especially in the hardwoods, if your 15 feet with the leaves down, you may be in trouble.

Campo,I used to think the same thing about climbers 10 years ago. With 30 some deer in the freezer out of stands to my credit, 20 or soof them have been from a climber, with a whole bunch taken within an hour of getting settled in the tree.Having a climber during rut time is one of the greatest tools in my bowhunting arsenal. I wouldn't be without one in November.
