1. You should follow your company SOPS (whether you agree with them is another matter!)
2. Make sure you state what is unique. For example if there is an emergency turn for the runway/airport (in the event of engine failure) this should be briefed.
In (2) if you mention the emergency turn and say nothing else other than "standard" this is about 7 out of 10.
If you brief all the standard stuff but dont mention the emergency turn this is about 1 out of 10.
For the descent and approach brief for what you really think is going to happen. So if its a gin clear day and you expect a visual then brief for the visual - you can always back up and say, any problems etc we will do the ILS as per the fleet. As said above if you company SOPS differ from this then you should follow the SOPS and/or become Head of Training/Chief Pilot and change them!
