I tried blind solving a while back and I got as far as to solve all of the edges, but memorization was just too much for me to work out doing a full solve. I think it had a lot to do with the fact that I was using the speffz system, and coming up with images for letter pairs like ZV or KQ was very difficult.
I’m thinking of using a new system since I already have a PAO set up for 2-digit numbers. Any ideas? Has anyone done anything like this that they could share their system? One option would be to simply number them 1-24 and use a person-object system in order to keep track of parity.
EDIT: I miscounted the number of locations as 20 instead of 24 and it made my post confusing
