If you don’t want to mess around with multisig but still eliminate a single point of failure on the whole stack, you can also just split your stack across X pairs of cloned devices. Oh yeah and don’t forget offsite location 3 for locked and tamper evident plates with your forever seed backups on them. I vacuum seal the steel plates for protection against the elements and bury them in those little 9x6x5 pelican cases with a lock on them. Just have to make sure they can’t be found by anyone but you and your heirs and that you can always get to them. It’s easy if you have land. Another thing I like about cloned signers is that even if you do keep on at home, you could crush it underfoot or throw it on the neighbours roof if you needed to, and you’d still have a cloned one somewhere else.

Yeah I figure might as well go overkill now rather than scramble when we 10x and I realize the whole thing is riding on a single signing device and single set of steel backups. I can’t wait to go to a garage sale years from now and find a set of seed plates that the person’s relatives have no clue what they are.
