 Heard about that SeedXOR + pass phrase though? 
 I’m fine with multisig from different vendors set up 
 You still have a single point of failure, but but I love this setup.  
 Elaborate? 
 If you lose 1 of 48 words or a single letter from your passphrase, you HODL forever. 
 Seed XOR is an excellent way to make a redundant backup of your seed however. Passphrase risk can be mitigated by using pre-spelled BIP39 words on the ColdCard so I wouldn't panic. 
 Put copies of two parts in various locations with small bounties but never all the parts 
 I stop using my coldcard once the mk3 quit getting updates. 
 At first, I used a 2-of-3 multisig with CoboVault, but the wallet stopped working because of some update. I didn't lose my stack because I had access to the other two keys and I was able to use the CoboVault key with a Seed Signer. 
 I also had a cobovault. Same situation for me. @SeedSigner is what I recommend now
