Flyburg
It depends on if my route overflies all the NATs or not. Or if my diversion alternate will have me fly from my random route through the NATs for the day. It is a pain but it beats the alternative. If I am on a NAT then I don't plot the other tracks because the contingency procedure will allow me parallel my cleared track until I am below the rest of the NATs and at that point I would continue to my alternate. We also uplink our oceanic clearance and we have CPDLC. I'm not suggesting to anybody that we use the plotter a sole back up to make sure we don't have a GNE, (even though we do plot our position 10 min after a crossing fix to also give us another crosscheck). However its use is invaluable should you have to do a driftdown when on a random route overflying the NATs.
