I enjoyed both videos. In the photo below is something, some of you might recognize. I found them at an "Olde Time Store". The are little twists of paper that have a product in the ball part that snaps when they receive a percussion. Either thrown at a hard surface or hit with some thing like a slingshot, shot. They are right around the 8-9mm size. I like these since I don't have a high speed camera to see whether the shot hit the string or the shot. And I have hit the string on a target many times( not saying you hit the string Hawk, but it occurred to me). The pop verifies a hit because they don't pop unless you actually hit the ball part. I mount them at the end of a string with tape.I don't hit the ball often. So my hat is off to you Hawk for hitting the first shot.
