I don't buy lottery tickets, but let's just say I came up with a bunch of
money. Enough to satisfy my aviation needs and wants. One of the airplanes
on my list would be something like a Pilatus PC-12 - a big, pressurized,
turboprop single which would be an outstanding X/C aircraft for any
destination in N. America.

As background, I've got about 1,000 total hours. All VFR, with a bunch of
X/C trips. I currently fly an RV-6 which has a lot of dyamic performance,
but is a very simple airplane. It and rental Cessnas, my old Tomahawk, and
a few other similar aircraft are the limits of my experience.

Beyond the obvious ratings issues (Complex, High performance, IFR, etc),
what would a logical step-up sequence be for moving up to something like the
Pilatus? Gain proficiency in an Arrow, then move on to a Malibu, then....

Just curious about what additonal training/experience it would take to
effectively transition to something like the Pilatus.
