A-321, if that is you attitude to safety I would hate to be pax on your flight the one day you need to handfly in raw data and bad WX. Will much rather fly with the guy that keeps his skills up to standard in the daily life.
I don't think anyone experiments in busy airspaces or bad weather, but SOP in all companys I have flown for encouraged crew to maintain skills, but do it
where appropiate and when BOTH pilots are up for it. THAT is airmanship, and it is very healthy!!!
Stay safe
