Written versus Mental
Undoubtedly, you've learned or developed a mental checklist, or, if not, you likely will at some point. There's the famous GUMPS as a before-landing acronym (gas, undercarriage, mixture, prop, seat belt and switches) and CIGAR as a before-takeoff one. And if you don't have a mental checklist for "in-range" or at final approach fix inbound, start developing one now. The mental checklist will serve as another valuable layer of redundancy and perhaps even a lifesaver in a critical situation with little or no time to consult a written list.
