I just about trust myself with a single sig hardware wallet. With multi sig, I'd almost definitely fuck something up. Nope, no thanks!

the backing up of multisig has issues. Even the BSMS are not compatible from one wallet to the next - they create them differently. After my extensive testing of multisig, I said “fuck that” also and use a complex 25th word instead.
Well that's why I'm testing. I'll never be comfortable until I do. So I create, put $20 in, delete, recreate, move out, move in, try it on different wallets and hardware, etc
