NR:
As anyone will tell you, once you are in fully developed vortex ring state, not the inscipient stage, the cyclic tends to have little or no effect until you reduce power (ie. enter autorotation). So for my money, it would be reduce power followed very shortly thereafter by forward cyclic.
I also agree with the comment on the Chinook recovery with sideward cyclic.
