For sure -- different mnemonics suit different people.
I remember reading a book of memoirs by the novelist Anthony Burgess, one of whose hobbies was learning foreign languages. He mentioned that in the course of doing same, he often thought up mnemonics which were so complicated / just plain silly, that he'd be embarrassed to tell them to anyone else. One which he did vouchsafe, was: in the course of a spell of employment in Malaysia, he set about learning Malay. A word in that language is "bermastautin", meaning to settle, or take up residence, in a place. Burgess's memory-aid for this, was: he thought of a Scotsman, with a fondness for the "stout" variety of beer, domiciled out east. This imaginary character walks into a house and takes possession of it, doing all the territory-marking stuff; then sinks into an armchair and calls to his native "bearer": "Ah'm settled here; bear ma stout in".
