Such a witty retort.
If you want to hide behind "I'm not a test pilot" fine. All aircraft performance numbers were demonstrated by company pilots. If they're not safe, take it to the FAA/Boeing. You should probably limit yourself to half weight, half crosswind, and double the amount of runway needed. Where does it end? If someone isn't comfortable with the performance of the airplane, maybe they're not ready to be captain.

I mean everyone is just a line pilot, not test pilot. I believe I can operate Flight Sim within the performance limits though so I'm good.

@EagleATR- don't worry about the dispatcher calling you names, your airplane does it for you. Yours is different though. You had numbers that said otherwise. The ROA case was about being comfortable.
