One of my pals is an airline captain,he also flies a Pitts.
His advice was not to waste time and money on spinning, but to have some aero lessons.
Frankly this is ridiculous. Any Aerobatic pilot worth talking to will tell you that spinning familiarization is the core of any aerobatic flying. You cannot start flying ANY aerobatic maneuver without a good grounding in UA and spin recovery.
Being an Airline captain and owning a Pitts does not imply sensible advice. (This is being written by an airline pilot that has owned Pitts's)
Fly safe Get trained! Money spent on Spin training is not money wasted, but money invested in your future well being. (And that of your passengers)
I can attest that my Unusual Attitude and emergency spin recovery training that I received from Alan Cassidy at White Waltham many years ago, saved my life last year. Practicing for a display the aircraft departed into an unknown auto-rotation. The basic Emergency recovery technique taught to me, was the difference between being here and not.
