No argument there 737....however a mneumonic is just as much a valid checklist as a written one and imo more appropriate to single pilot ops.
They should also be short and concise...killer items only...like boeing checklists.
I put a SAFEGO type in my Bonanza...mostly because it's online at an aeroclub and flown by relatively inexperienced pilots who are never 'current' in any true sense. They're a flip type with a couple or three things under each tab. Perform a scan of two or three related items and them flip the tab to cover said items.
