You also won't find many IR helo pilots, apart from those employed on multis serving the oil rigs. An IFR chopper is slow, and ATC doesn't like trying to fit it into a stream of 250kt jets for an approach to a busy airport. Just trying to remain current on ILS was a pain, I never got to fly one to minimas in Sydney because ATC vectored me out of the way from 5nm because I was only doing 145kt.
