Do you guys BIP38 your paper wallets?
I do. BIP38 is a important feature in paper wallets. It protects against theft of your Bitcoin and is relatively hard to crack if you use a strong one. However, you do have to remember the password. The best practice is to write it down and keep it somewhere safe.
It's not safe to write down your passphrase. Then it's like you don't even have it. I rather make and remember my passphrases as a sentence, and I add a few symbol characters. So with a password of 30+ chars it gets uncrackable in my lifetime. Which is OK

How is it not safe? If you don't write it down you run a serious risk of forgetting it. If you write it down on a random page in a book on your shelf someone is hardly going to find it. I would even go as far as to copy private keys as well just incase something fucks up.
