Kendall, I finally got around to measuring for a string. It needs to be 55" total end to end. As for colors, prefered is grey with green stripe. but just black, or just grey is just fine. The nocks are red. 4 of em. They are the glue on type. the arrows are very old and the size says micro flight 7. If you nont have the nocks ill contact three rivers and try there. let me know what I owe ya!!
