Well, there you go then; Northern Flyer has blown my theory with his own personal experiences. Sorry to hear about your bad luck fella and I hope something comes up again soon. What I should have added is that I know a few low houred guys who managed to get some pre-sim check jet practice and found it invaluable in gaining the job. They also admitted to having had some practice beforehand. Just fortunate I suppose?
What works for some obviously doesn't work for others! Nothings ever 'black and white' in this game.
