SPIFR is as demanding as any flying there is. It requires constant practice in order to be reasonably proficient, and the constant practice isn't possible in EMS, where there is relatively little flying at all. SPIFR machines are mostly for recovering from inadvertent IMC, but that's where the most proficiency is required, and where lack of it will kill you. In short, SPIFR machines are for eyewash, just a marketing tool. Many programs with SPIFR capable ships are prohibited from filing IFR. There is actually a point of view that they're more dangerous than less capable machines, because they may tempt pilots into flying in worse weather. With a 206, you know without question that you don't want to fly into weather. I'm not sure that I subscribe to that view, but it seems that some do.
