I will say the recent firmware update last week helped with the NFC / Nunchuck Bug where it would be highly sensitive to signing transactions

You can also use air gapped micro SD with sparrow on the same wallet with CC, so that option is opens

I use mainly nunchuk for incoming which is super easy to copy and paste wallet addresse to receive. No signature necessary on incoming.

To engage the wallet via cold card nfc it’s one tap to set up the wallet itself on nunchuck initially.
