What ever happened to talking about what you were about to do. SOP here says, 60knt call, Captain assumes full control, de-selects idle reverse and when required stows speed brake. After landing check-list is at the captains call. Most often a subtle reminder to commence the list is in order, such as asking or a gentle rattle on the flap handle as you pull the list out in front of the captain. Make light of a forgetful pensioner!!!!! he is only human.
