As I was watching you guys practising I hit on the idea that I could record some videos of me cracking in slow motion. 15min ago I came back from the gym with videos of several different cracks (cattlemans, coachmans, flicks, slow figure 8, fast figure 8, volley, and a bit of victorian cutback with underhand flick) both in normal speed and 120fps, both from the side and from the front. Tommorow I will try to edit it and upload these videos to YouTube, and I will post all links here. I hope that will help you with understanding of these cracks, movement of the whip, and the body.
