Keef: How right, it doesn't matter what mnemonic you use so long as it works for you.
Just one follow-up point, Pitot Heat ON during power checks is OK, provided you get rolling shortly thereafter, otherwise a long hold without cooling airflow could leave you with a burnt out element (especially on types cleared for flight into known icing where the pitot seems much hotter during the pre flight check!).
It is for this reason that turning it on during the pre take off checks for the DI check (in case the electromagnet of the pitot heat affects it) and then off until lining up seemed a better option to me. Each to their own, however!
