When do you want to blast the left arm off the chest? If you want to do it early go with TSP. If you want to do it later do a plane shift.

Daryl touches up on the difference between elbow plane and TSP, but misses the mark. The reason for using an elbow plane is more pivot control and more thrust through impact, better balance and more leverage into the follow thru. And of course more controlled usage of accumulator #4
