This is a great question. I'm 6'5", 250lbs, and was fortunate enough to sit in the right seat of a Citation X a couple months ago. It didn't take me long to realize that if I was going to be making a career out of that, it would be one painful journey...hunched over the controls, knees feeling like they're up around my ears. I haven't had a chance to try anything else out, but in a few months I'll let you know about the EMB 120
