Thanks for your thoughts chaps.
I am of course in agreement with you regarding the Overspeed Prevention drill.
However, this as you describe above suggests consideration of using the speed brake as required.
The Overspeed recovery is very specific in that it states that as soon as speed exceeds Mmo you use full speed brake. I just think its badly written and at least needs some italicised information to ensure the SB is used carefully and slowly.
