Always remember - simplicity beats complexity for security setups. Historically, you’re much more likely to loose access to your keys due to your setup being too complicated than you are due to someone compromising your single sig wallet.
It’s a great rabbit hole to go down and play around with, but make sure you fully understand it and are comfortable with the extra complexity before you secure life changing amounts of corn using it.
For most users, single sig cold wallets will work perfectly fine.
