3100 hours here on the 200.... had it up to FL390 pre-restriction. Scared the bejesus out of me. Any bump you hit and it just sinks in. All I wanted to do was get back down lower in some thicker air. The CA couldn't feel it though- didn't understand why I was nervous. Go figure.
I was also the last guy to fly with the Pinnacle 3701 CA before their fateful flight...
