" There are
virtually no airplanes that will spin without poor coordination…"…

this is the kind of statement that could get people hurt. some people might read that and believe all that is needed is to keep the ball in the center and proper rudder use will do that every time.
One experience,
 your in slow flight ball centered and slowly increasing the angle of attack, one tip stalls and the resultant drag increase is greater than the rudder power available now your spinning .


another example to think about 
Two experienced pilots tour with a 1930 design to airshows to demonstrate an airplane. one has 70 hours in type the other several hundred hours neither has ever done a stall in this plane. are they stupid, afraid or do they recognize and evaluate each plane and maneuver separately on its merits and risks?

 I still don't really understand everything Ive witnessed and experienced .there are so many factors that interrelate that even a computer doesn't get it right all the time. Yes the ES flies nice but the columbia after several successful tests had one spin that needed the spin chute to recover. it was finally decided to go spin resistant  rather than wrestle with all the factors involved in spins.
