I am a little late too this thread, but here is how I deal with that situation. I tell the Captain that I would have no problem flying the airplane his way. I have to learn how to fly it his way, so he needs to be patient while I am relearning how to fly. I also tell him that since I am relearning how to fly I am more prone to making a mistake. Now you have to stay on your toes without relaxing to catch that mistake I am sure to make. The next word out of his mouth is usually, " ok do it your way."
The rest of the trip usually goes without a hitch and he has more respect for you since you handled the situation in a nonconfrontational manner.
