You just spoke my mind! And you put it in words that I wouldn't have put better myself!
I am promised a command in my current employer (corporate) in a year or so in a B737-800w . But I know for a fact that the idea of not flying a wide body aircraft will haunt me for the rest my life.
I know the airline will squeeze every bit of my time and energy and thats fine; I am well prepared for that. However, I am expecting a lot in return in relation to my career (TRE/TRI, Safety, Training, etc)
I believe a pilot career and experience is not complete if he or she is has not worked for an airline. It will not make you any less of what you are but experience wise it is very tempting nowadays.
I hope my two cents was worth reading.
