John Halle,
     And John, thanks for your  enlightening discourse on spins, I just hope you have the time to rashional it out after your A/P dumps a "hard up" on you in IMC.  Sure, I should have caught it and Yes, it was pilot error, but if bearing my soul helps someone elses awareness, then you miss the reason for the original post.    The fact that , in my case, anyway, the recovery was pretty well straight forward, proves that it can be done with "conventional" techniques.  They are not "benign" because of the rather large altitude loss in my case in IMC.  If you have some real experiences/ data to add to the discourse I'd like to hear it...
