HFD.
True enough, but my concern is that an unintentional departure towards a spin is usually going to happen relatively close to the ground in normal operations, since this is where the pilot will be at the slower end of the speed envelope. One less thing to do might just be the difference between recovery and a hole in the ground. In any event, we're all duty bound to state that the spin recovery in the aircraft flight manual is the one to use.
