From what I've been told before, Jet U's only bridge is Pinnacle. 9E is hiring it seems mostly Jet U guys, considering supposedly they teach Pinnacle procedures only there. But I agree with the previous post. You'd get much better experience and you'd learn to appreciate the 121 job more after flight instructing. You wouldn't stand in awe at all that "IFR stuff we have to do in the winter." (Yes, I've actually heard that one.)
