I'm not saying never use them, just that in relatively simple aircraft I feel they can hinder more than they help. It feels stupid to be using one in a Super Cub, or even a C 172. It encourages mindless flying.
You can go through a written checklist without thinking at all about what you've done. It's like that feeling of leaving the house and then wondering if you've locked the door. In the end, you always have, but you can't remember doing it. I never have that feeling if I do a left to right cockpit check of all the relevant bits and bobs.
Anyway, I knew this would draw some response.
