go as high as you can go safely(....depends on the tree thickness, type,knots, splits, wind.......)unless your right on top of your intended shot. trajectory can make things tricky if you dont practice these shots. I've made some great ground blinds this year out of cut saplings & brushand am hunting on the ground more and more...im seeing more deer this year as well, due to being able to set up anywhere anyplace in about a half hour...come back 2 days later2letthings settle down....and kill!!!
