Fair enough, I have never flown a Cirrus. It's the new way I suppose...
I write a number of Flight Manual Supplements, which are approved as a part of an STC on an aircraft. When I write these, I review them, and ask myself "what can I cut out of this, to make it brief, effective, and safe?". Airmanship has to play a part in getting and keeping a plane in the sky safely. The longer a checklist is, the more likely it'll be skipped or ignored. I focus on those things which will result in an unsafe situation if forgotten, and are unique to that aircraft, or class of aircraft.
I sure would rather add one item, of "controls free and correct" than four or so items of "remove control lock......". Chocks and tiedowns - nope! let the pilot feel the embarrassment of trying to taxi a restrained aircraft - they'll never forget that again!
If a new C 150 pilot would like to use a checklist to build airmanship, I'm good with that. It's a tool, not a crutch....
