I have been reading all this with interest, lots of valid points over the last few weeks and one thing strikes me.
If I was flying to imc minima, at night, over sea, mountains or some god forsaken part of the world I'd rather have 12 cylinders,(or maybe 8) 4 mags, 2 props and the potential of a nice smooth underside rather than a chute - which may, just when you need it, fail to deploy.
I may well be wrong but a pilot who can afford a Cirrus can afford a twin surely?
