BOHNING GRIFFIN VANE HOT PINK 40 PK. The Griffin Vane is designed specifically for olympic recurve archers. The twisted ribbon design aids in immediate arrow rotation and the minimal surface area resulting from the cut-out profile provides a stable & accurate flight in variable, constant, and zero wind shooting scenarios. Weighing 1.2 grains the Griffin can be fletched with a standard Pro Class Style Jig using glue or tape.
