I hunted about 15 feet for years and 2 years ago i started going up to 25 (my pull up rope is that long and I climb till it gets tight) I have seen and killed alot more deer since I went higher. i practice at this hight alot pre season as well. for practice i go up a tree till my pull up rope gets tight and shoot at milk jugs that i have strewn around my yard. have my kids gather up arrows and send them back up to me for another round of shots
