25 feet is about my max. I don't like high places all that much myself. I use a climber mostly. Seems like every year I go through the same break in period. Early in the year after having not sat in a stand for months I'm not comfortable much above 16-18 feet. As the season goes on and the vegetation dies off I start getting higher. I'm usually 18-22 feet. I seek cover from tree limbs, pulling in small under brush trees with a rope and tie them off to my stand or tree. Sometimes I work bushy limbs into the stand and climb up with them for cover.
