The road to undermine the commanders authority is a very risky and dangerous one. 120.4 makes a very valid point however. I have flown with captains who upon approaching innocuous cu bark "tell em were goin 20 left for weather" and feel because number two will make it so, they just make the turn, even thiough the poor sodin` f/o cant get a word in edgeways. The lengths I`ve seen some people go to, to avoid fairly benign weather is at times outlandish.
