skin the wings use a circular cutter and slice the cores into bitesized pieces, they actualy sell them as imitation scallops in some countries, would be good skewered on the grill with shrimp and cubes of sharksteak blackened.
other than that the best shark bait you can get.
caught one that taped 5'3" tip to tip my last trip to OBX on a rod and reel, was a real workout getting him in then walking him 700' from the end of avon pier to the beach.
