Hi Janis, I would highly recommend having several memory cards. Memory card failure CAN happen. It never hurts to backup to a laptop every night... just in case of card failure. I have had a card fail. Fortunately not on a trip.
10-CR-1 in Holland March 2020
12-Which? (I'm not sure which cross this is from)
12-KE-7
11-JJ?-5 The goal is Orange that doesn't fade. Orange Delight (09-HT-1) is a solid step in that direction. 11-JJ?-5 is small, but possibly could help
12-FD-1 appears to be a good yellow. Time will tell how it does. I already have a couple of other yellows converted to polyploid...
