Never thought that my question would result in this healthy discussion.
To stay current in a particular skill you will need to practice it until you retire. I keep track of the way I fly (auto/manual/autoland) approaches in my logbook. For me it is a way to stay away from doing the same routine everyday and forgetting the other. Complacency kills, and in current operations it is very easy to get complacent.
Thanks for all your reactions.
