midline would seem to me to be the best way to ensure sufficient ROM...
BTW as a self-confessed duck walker, my lordosis is made up of forward tilted pelvis, limited hip extension (with tightened and shortened quads, long hammies, and not enough lower abdominal strength to tilt the pelvis back far enough) - this means I need to work on strengthening the long, weak muscles, and lengthening/stretching the short, tight ones.
Until I do this, I have to compromise on the posture I can achieve from thoracic and cervical area as my lumbar spine curves more and the other two have curve to accommodate it. But remember, posture is dynamic - it's there to serve us and to form the basis for our movements - so we're aiming for an efficient posture from which to do the movements we need to do.
