I find the differences in opinion on either side of the pond quite interesting. For example, we've recently changed our departure and arrival briefing to a more succinct format, with the expectation that the other pilot has a firm grasp of the SOP. Thus, we really don't go over any of the stuff that's already in the SOP. For example, my arrival brief typically takes 20-30 seconds, and that's going at an unhurried pace. From what I've heard from friends in other parts of the world, that's criminally short, but yet we manage. Not saying that our way's the best way, but it does seem more efficient.
