go high enough to where if you have to jump out it wont hurt.....i had one of those 1st time experiences last yr.....climbed up the tree about 10 ft and the bottom lost grip and fell to the length of safty rope, i jumped out hooked it back on and climbed up. 10 min later shot a doe at 20 yds. im not going more than 10-15 ft cause #1it takes to longand the other is why be a sniper in the woods, let them get close it makes for better stories.
