All opinions are welcome here.............as for the (magic self labeled) Vuichard technique; my Mountain colleagues & I have tried many, many times, sure it works OK (just) during the onset of a pussy footed SWP or IVRS , but once Your in a full blown skid mark serious VRS; then the Vuichard technique is as useful as licking Your microphone wind sock for a recovery. Be warned the Vuichard technique is Bollocks, it won't do diddly squat for you in full blown VRS.
Moral of the story................stick to what works & you'll live longer; 
'If it ain't broke? Don't fix it'
When Your in VRS:
1. immediately & abruptly Pole forward (a good hand full of forward Cyclic)
2. leave Power (Collective) applied &/or add some more to the red-line
3. keep her straightish with pedals
.........works like a charm, every time! Tried, tested, proven; too many times to count
