A very effective tecnique to deal with VRS I have used and taught in light helicopters in mustering operations for a long time now is to fly the disc rather than the airframe. When you become used to recognizing the early stages of VRS onset it is quite simple to take the disc into clean air and avoid the problem, in most siuations it usually means you just have to move a couple of feet into wind regardless of which way the airframe is looking.
Also it is important to to keep your manuvering in a relatively flat plane so as to reduce your opportunitys to encounter VRS. Lots of height changes high and low are no good.
