I'm with Miserlou.
When I started flying skydivers (in a 182) I made my own checklist and the bloke who owned the airplane asked we what it was. When I told him, he took it from me and said "If you need that, you shouldn't be flying the airplane". It took me a while to understand what he meant, but, as Miserlou points out, before takeoff, landing etc, I checked the essential items using a flow pattern and the rest became pretty much like driving a car.
This isn't to say you shouldn't use one. It's more about putting the checklist in perspective. If I was fortunate enough to be throwing them out of a Porter, I probably would use a check list.
During training we have to stress safety for obvious reasons, but at some point this culture has to give way to airmanship.
