Ego Vs Professional Responsibility
Well speaking for myself, the flight deck of a wide body aircraft (or any other vehicle for that matter) is THE ONE place where ego has absolutely no place.
My post stated that you should, as a matter of professional responsibility, be fully conversant with all the recommended techniques and use the most appropriate one depending on the circumstances in which you find yourself.
As to ULR flying and maintaining competence/proficiency. In Ek we do 1 or 2 a month so it should not be a problem. However, I agree that if you do nothing but ULR stuff maintaining proficiency is not easy hence being familiar with all the various techniques, or tell someone and get into the sim, or be a grown up and bid, if possible, for less ULR flights thus taking responsibility for your own competence.
It is not brain surgery after all.
