If your goal is to try and top weather, then stay out of the 200. In the summertime, you usually crap out in the climb somewhere around FL270. I would rather be at 12000 fighting my way through it, then at F300 going slow and wishing I had more power, altitude and airspeed. The only jet that is worth the move for is a 900. And only because of the cities it flies to.
