Asking for a proper brace height is, IMHO, a way to get off on the wrong foot and here is why.
To determine the brace height of a bow the first step is to measure the bow nock to nock along the bell-don't pay any attention to the AMO length.
Then get a string three inches shorter than that measurement.
When you string the bow with that string you will have your starting brace height. That's what you need.
Then start shooting and twisting the string tighter until you obtain good arrow flight, no arm slap and minimal noise.
That will be YOUR brace height for YOUR bow and it can vary by an inch from what others experience as it is truly an individual thing.
I speak from an informed perspective as I have three 62" Wing Thunderbirds plus a Don Adams's copy. The brace heights between all of these are well over 1.5" apart...that's proof positive that everyone's suggestions reflect their personal reality that has nothing to do with where you will end up.
Bottom line? Tune to your shooting style and find your own brace height.
I trust this is of some value.
