Here's a quick drawing that is very pathetic! But it gives you a rough idea.
Picture 3 shows the slingshot at the top and makes the middle section of the trunk very straight and also takes the movement at the bottom away. This option is the worst of the bunch from the trees standpoint.
Picture number 2 is showing some promise. Why? Because it shows the lower movement in the trunk, the movement comes to you. The middle of the trunk has movement now and the slingshot at the top is no longer an issue. At this angle the trunk leans right instead of away from you as in picture 3.
It also allows for the jins to be used in a good way and for the branches to be used in a way that will form a pleasing tree.
The red arrow on the left is basically the angle you took the picture on. The arrow on the right is the angle I would propose to use so that you are looking into the lower movement and the trunk comes to you and to the right instead of just to the right. This adds dimension which lacks from many bonsai/trees out there. This will also maximize the movement of the tree.
I know it is hard to convey on a forum as opposed to in person...but I hope you get the jist and my poor drawing gives you a rough idea, lol!!
