What makes me laugh about this whole "are ex turbo-prop guys good enough to be allowed into our special club" b@llocks is that it is no different from the ex military guys who say "are civvys who never really had our expensive training good enough to fly with us"
Most civ background people aren't exactly fans of ex mil who say that sort of thing..
As ex military and ex turbo-prop and ex Airbus myself, I would just like to say that prop is harder work almost all the time, different climates are no big deal, the job is not hard, and if you can't find the time to read the paper on long-haul then you have no business in the pointy end of an aircraft.
