SWP, VRS and the Vuichard Method  

At annual training recently we did our usual recognize and recover from SWP. Climb to 2500', turn so you are lined up with a tail wind, bleed off airspeed to zero while maintaining altitude. At around zero airspeed the IP reduces collective a little to start a descent and says recover. So we don't ever get into SWP, but its about learning what it might feel like and recovering by lowering collective a smidge and flying out of the desecending column of air. 

I have asked if we can recover using the Vuichard Method and always hear its not in the training manual or something like the FAA have not acknoweleged it yet, so we don't do it that way.

Is this common in the USA? Should we be teaching the new (Vuichard) method? What does Bell teach?

I'm adding this link even though I sure most have seen it before, but the music is cool :-)
