let's agree to differ then......agreed it's a 2-crew op but if there are extra resources available then, in my book, use them. There might well be the occasion that these guys happen to pick up an error that might have gone un-noticed by me and my oppo...and, as you again well now we are all going to work tired on the 'bus. Your way works for you, mine works for me - hope that you don't ever make a mistake, I know that I do....
