Don't think of them as wallets think of them as transaction signers that hold your keys away from the Internet.

You don't need a transaction signer to store your bitcoin, only to spend or transfer it.

I selected 11 random words & used the seed signer to help calculate viable 12th words before selecting one. I then loaded the seed into seed signer & imported the xpub into Sparrow from the seed signer screen.

That gives me a list of receiving addresses for the keys & I don't need to immediately get a new transaction signer (I'm thinking a Bitbox).
