Since reading about this on here I have added a version of this to my pre-flight checks (glider). I point and say everything in the cockpit and then do the checks using the traditional mnemonic with the hope that everything will be in the correct state. It turns out to be easier as I am only doing one thing at a time rather than having to remember the mnemonic at the same time as setting stuff. I am not sure I actually need the mnemonic any more.
