One of the airplanes I currently fly is a 24D and it is a nice plane to fly. Not many 24D's around anymore due to the noise restrictions at some airports and the fuel consumption. Like many other straight pipes, this does require some finesse in fuel management and aircraft control, especially the CJ610. You have to climb and cruise at red line or you risk a flameout.
The 24B is a different animal completely, as is the 24. Descending out of altitude also takes some finesse since the pressurization cannot manage a thrust idle descent. You just gotta love them.
