Black Crappie friging nice Mr. Pogo.
Have you ever tried a serrated electric knife to filet them?
I know you have good filet knifes but the serrated electric once you get used to it takes it right to the bone and saves a lot of meat.
ADD: To store them down here we put the filets in a gallon plastic bag pour water enough to cover the fillets and a dash of salt. Keep the bags upright covering the filets in the freezer till they freeze. Hell they will last forever.
