I am with BelArgUSA. Human attention span is fairly short. Once line training is complete and checked to line, I give my copilots some credit for knowing the basics and SOP. Thereafter, anything which is standard I specifically do NOT brief for fear of sending them to sleep. It should be a given who will do what if an engine fails before V1 and what the clean up drill etc is - just like 'pull back and houses get smaller', we are supposed to know it and do it instinctively. Anything which is different or open to confusion is worth discussion.
I aim to keep briefing to less than 30 seconds. e.g. "Flap.. bleeds OFF takeoff. High ground on left so we turn right. SID turn RIGHT to heading...at..miles but if engine fails turn EARLIER to heading...at.. miles. Climb to.....ft before clean up. Any questions?"
If it's a straight ahead flight path I would probably only state the flap, bleed configuration and clean up height because the rest should be obvious.
