Another thing to consider. Just like a longer A-A bow is more stable in resisting a canting-type torque(with the axis along the arm), a longer brace height puts the cam/idler and end of limbs(therefore more weight) further from the pivot point at the grip(moving the inertial center toward the shooter). To me this would resist the side to side torque(with the axis down the riser vertically) better than a short brace height with the cams closer horizontally to the grip. This is the same principle as the long target stabilizers on the front of the bow to give inertia and resist torque. Maybe I'm way off base, but it makes sense to me.
