It seems possible to get a Super Puma into VRS starting from >500 fpm rod and <30kts according to the accident report from G-WNSP.
Now, back to using your grey matter: recovery #1 requires you to lower the collective, push nose forward and then raise collective again. Recovery #2 requires you to bank into the upstream of the vortex and not lower the collective, but raise it directly. Which one of the two do you think would lead to less altitude loss ?
