I do the control check full range (I see some folks who do not) and I do it fairly abruptly...I want to ensure that any abrupt inputs I may to make in the air have already been tested on the ground. I have a friend (USCG) who was involved in the clean up of that AK thing off of LA, and I flew with plenty of folks who knew the crew on the mesa B-1900 that over-pitched at CLT...it gets to me a little bit, I don't take flight controls for granted.
