I do whatever I need to do, to get the bow to shoot well(which is usually not much),,when someone is having an issue with spine etc, sometimes the bow is not designed well, the string is laying on the wrong side of the handle etc etc, if the bow is built well,, it will shoot a wide range of spine,, and not be so sensitive to brace either,, shooting a fairly low brace with ease,,and shooting longer or shorter arrows as well,,forgiving
if the arrow pass is too wide,, or release is bad, then raising the brace can compensate for alot of issues,,,but at risk of compromising the life of the bow,,or the performance,,
shoot a bow at 5 inches though the chrono,, see how she does,, now brace it up to 8 inches and shoot 100 arrows,, go back the chrono and you will see why a high brace is over rated to say the least,,make the bow well and you won't have to brace it high,,,
