Finally can you please not turn this into some kind of American love in? Bubbers is really good this, SSR is very experienced that...if our want to back slap and high five each other do it in private, hoo yah! Fawning is soooooo last year.
So instead, I see you prefer to change this to your typical 'bash' all people that disagree with you thread.
Use the flap settings that book tells you to use. Can't be any simpler than that. Once you change standard FAA/Company/manufacturer's procedures, you cease being a line pilot and become a test pilot. We are not paid to be test pilots.
Except of course if you are paid to be a test pilot.
