I have some hang-ons set at 16-18 feet where I have used my 16' stick ladder! Others, I add a few screw-in steps to get to around 20-22 feet. Anything above 24' or so, tends to give me nosebleeds. LOL!! Height does play a role in most hunts...deer are becoming programmed to look higher and higher in trees when they feel hunting pressure within a certain area, especially if a hunter has missed a shot at then in a given area!! Deer can be extremely smart!
