I would not say it's a different take on Vuichard, it's more so the reverse. For instance, when longlining and moving your bucket into a dip site, if you feel any early stages of onset coming in, your natural reaction is to move the aircraft sideways. You have your head out of the door and that it the natural way to go - sideways. It's probably been used ever since we started lifting things on lines with our heads out the door.
Whether you believe in the Vuichard technique or not, learn how not to get in the situation and learn to identify the early stages of onset. It is good that you got exposure at a low height.
There is a video around somewhere of an incident where a Md900 fell off the top of a building in the Gold Coast in Australia whilst lifting air conditioning parts and got into VRS. The pilot used the side slip technique to gain control at the bottom of the 'fall'. He was/is a high time longline pilot from NZ/BC and would have no idea who Vuichard is, let alone how to spell it.
