What memory card are you finding to be the best/fastest for use with the Mini 3? I have tried several all get a message that the "card is slow". I'm wondering how the still picture performance should be with a "fast" card. I tried using the mini 3 to shoot some fireworks tonight and it was painfully slow to save just one picture. If I did a burst I was missing the next 8-10 fireworks while I waited.
