I have 2 tapsigners on the way, which will leave one trusted device. I'm a paranoid who won't put any bitcoin behind a device I haven't been through the recovery process for. That means I'll have to lose trust of one private key then use the other.

I used a combo so that even if i lose one of the cards, the other plus the device key is all I need to recover it. So neither card is a single point of failure, and neither is my phone.
This is a compelling argument. Must acquire.
So basically a two of three mobile multisig?
Actually the one im currently on is just a 1/2, but using my mobile key as my account key for access. So the mobile key is a barrier if anyone gets my phone, but its not attached to the bitcoin.
Im still experimenting with trade offs, but just really loving the Tapsigner as the prinary signing device with day to day use. Probably a 2/3 is the best all around for security and ease of use.
