Mark,
I agree with Mark's assessment that the SS is more affected with the "Yaw Sensitivity". As one of the early owners of the SS model which is equipped with a different steering system still has a yaw problem when making power changes and sometimes even in cruise flight.
My SS has a front wheel with direct steering that falls out of battery and locks into a streamlined non-steering mode when there is no weight on the nosewheel. I believe that this feature allows the additional yawing moment caused by the turning of the front wheel in flight to be eliminated from the equation of why the Tornado has a "yaw problem".
I've found that even with this additional feature of having the front wheel NOT connected to the rudder pedals in flight the tendency to hunt in yaw is still prevalent. It's been explained to me that the long slender nose of the Tornado provides some blockage of the airflow over the vertical stabilizer giving some tendency for that surface to "hunt" for smoother airflow off the axis of movement.
Anyway, I too had flown the 2S that Mark and Kimberly are referring to for more than 10 hours and found too, that the yaw sensitivity, both with and without the front pant fin, was bothersome but not overly critical for safe flight...only a idiosyncrasy for some models of the Tornado.
As an aside, I too flew the PC-12 out of the Salt Lake area that Kimberly was able to fly...although it was very quiet and flew nicely at 250 knots at altitudes of more than FL 200, the owner still chose the Tornado as his personal airplane. PC-12 is a systems airplane and "George" (the autopilot) did most of the flying. Handling the airplane by hand, like most larger aircraft, felt like driving a truck without power steering, as compared to the Tornado that is more like a go-kart with much better visibility! I've flown both and the Tornado is way more FUN!
