If your haul line is 25' (for instance)....and you attach it to your upper part of your climber......your platform will be in the neighborhood of 23' (if your rope gets tight when you reach your apex). Add YOUR height to that....and from the level your bow will be when you shoot....and you're hunting (shooting) from close to 27' (or more).
This time of year....I don't think that necessary or even "ideal". Just get good back cover and hunt. My opinion is....you'll miss out on more shot opportunities by being too high...than you will by being too low (as long as you're above 10'-12').
Give "that guy" who says he's hunting from 35' a medal....lol....and ask him how many times he's double-lunged a deer.
