I use elements of Giardano Memorizing System. It’s extremely effective. Multilevel locis were introdused here.
Thanks to this, you don’t need a huge number of locis to memorize a page of text.
I think you should give it a try at least. It does help train your brain. I was a pmemory graduate and instructor back in the days. Let me know if you need any help and ill be happy to help you.
