I don't have the book at hand for reference (shame!) but I believe 12-2 recommends Assembly point for Swingers as End. What advantages are offered over stopping at Top? It seems to me that using Top Arc and Straight Line Delivery Path is more complicated than just the Straight Line path available if one stopped at Top.
I recall there is a comment by Yoda in one of the videos that he goes to End when Swinging to differentiate the feelings between Swinging and Hitting. However, if one is primarily or only a Swinger, is there another advantage to going to End?
