Damn, I start using this strategy for some years now and I even memorized my seed. (it was difficult job to keep the order) together with the Walled address.
Long ago I've reinstall my Windows XP so many times that even memorized the CD key and used it for some time as a password
Used to mess around with IPv6 addresses so I manage to create a technique to memorize those addresses, i guess for the regular people this will difficulty.
Well, Bitcoin seeds are kinda meant to be memorizable, they aren't called "mnemonic" for no reason. Usually when it is mentioned, someone quickly points out that human memory is horrible and you should never rely on it, and they are totally right, but I think it's always good to have one more additional backup method. I too have memorized my seed, actually more than one seed.
But how did you memorize the address? Base58 sounds almost impossible to memorize, you have to remember the case of each letter.
