Shagbad,
That finishing move is something I saw Ben Hughes do at the WWAC International Convention in Oklahoma a few years back, and I loved it! I had never seen it before, and I believe he created it. So all credit goes to Ben Hughes for that move, and I have to say that he is absolutely mind blowing to watch.
What makes the arrowhead the arrowhead routine is the transition crack between each side of the body (each plane). It cracks right in front of the body allowing you to change the side of the whip the volleys happen on.
The 4 corners is not just an overhead volley. An overhead volley would be a step towards learning the 4 corners. The first step would be to thoroughly learn to do the figure 8 in the overhead plane, and keep it consistent and flat/parallel to the ground. Also get the overhead volley down consistent and parallel to the ground. Then work on getting an overhead coachman's figure 8 (slow helicopter), and keep it flat and parallel to the ground. Also, learn to start all three of those from both the regular first crack as well as starting it with the reverse crack.
Once you have those consistent, you can take the slow helicopter and learn to turn that coachman's figure 8 into a coachman's volley (fast helicopter). This is the base movement for the Hassett's 4 corners. The 4 corners is basically a coachman's volley in the overhead plane with a flick on either side. Or another perspective it is a variation of an overhead plane fast figure 8 on either side, and the variation is that the initial crack is a forward flick instead of a cattleman's, and the 2nd part of the fast figure 8 is a coachman's instead of a cattleman's. I hope that makes sense. The most important thing about learning the 4 corners is to build all of the basics up to the fast helicopter and learn to do it constantly and flat/parallel to the ground. Once you have mastered everything up to that point it is only a small step to learn to add the flicks at the right part on either side. Also, the fast helicopter is a strange twisting with the arm that is hard to get used to, and then adding the flicks to make it the 4 corners stresses that strange arm twisting even more, and is a little harder to get used to, but the arm movement is very important to getting the fast helicopter and 4 corners down correctly. So when you get to that point be careful not to overdue it, or pull a muscle. You will notice your arm muscles getting sore. I find it a bit easier to do with long handle whips, especially stockwhips since you can get the leverage and make full use of the keeper joint.
I hope that helps.
...perhaps I'll make a video showing all of the steps to build up to learn to do the 4 corners.
As for stockwhips, I've got a bunch of cane for stockwhip handles coming in a week or two, and if I can get caught up on orders I plan to make some stockwhips for fun and to have in stock.
I'm glad you all enjoyed the video.
