I think your path is good, but I would double the corner in tighter so I hit higher up the opposite long rail then coming off the foot rail and end up shooting the three ball in the side from around the foot spot area. This way I can take the nine ball out of the picture. So in other words I'd go head rail (short rail) then long rail (tight in the corner) then diagonal to opposite long rail before hitting the foot rail (where the cue ball will die off that rail so not much chance to get behind the nine ball) and ending up near the foot spot. Then play the three in the side follow to head rail and back out for the four in the corner. My shot doesn't look as good when I looked at the second picture in the original post as there is not as much angle as I had thought, still doable, but tougher.
Hope I explained this well enough, as I don't know how to draw lines on the table diagram, yet.
Yes, thanks for the thread as I enjoy these also.
