Oh good, I was hoping someone would bite! I might have guessed backpacker would get it, It is as he describes
(let me know how the slipped stall in the robin goes - I have theories, but very interested in the outcome).
We're all familiar with the concept that you trim for a speed, and if you vary the power the a/c will climb/descend, but remain at the trim speed; the elevator is just a larger, more authoritative trim tab.
To be honest I'm not sure that weight and balance do not change the position, however, empirically they don't change it a
noticable amount on anything I've flown. The simple fact remains that if the stick is forward of a certain point you're fat and happy, if it's back around that point you should be paying close attention.

The control forces are high and there is no way in a high speed stall you could move the control column to the slow speed position to achieve a high speed stall.
Pace, I suspect you may be mixing deck/aircraft angle with AOA the angle of the wing to the relative airflow. At higher speed, wing
DOES stall at the same stick position (as close as I can measure it), but at significantly more G loading (provided the wings don't drop off..) throw in a bit of rudder and its called a flick or a snap depending on where you're from. Not something to do in a PA28, but they fly by the same aerodynamics as the pitts, decathlon etc.
