Well I was enjoying an old match with Lassiter and Crane and noticed on one shot Luther pivoted, maybe just adjusting a bit, I do not know as I do not do that pivoting move and use the shaft method to aim. But for your eyes only here is the video, at around 9:15 you can see it, I have the video to start from 9:10. http://youtu.be/-XVagtZlfZY?t=9m10s
