Topentorque: eagle has it about right. The older heads on helos only allowed you to "regain" control, if, IF, that is...the selection of fwd cyclic was long and sufficient enough to "blow" the turbulence going on around the root and emanating outward...back away from the disc and placing you into cleaner air, thus allowing some form of recovery. Newer head design makes the above statement happen more quickly.
If you are able to confidently apply fwd cyclic in the knowledge that you will come out of VRS...may I suggest you are not in fully developed VRS
