Which is faster? Lean back or Sit up

In this video, Ken compares two common styles; leaning back and sitting up around the back-turn. The back-turn consists of two main parts, the "back" or finish of the drive and the "turn" or change of direction.

The way you carry yourself around the back-turn has a significant effect on the boat, and on your ability to flow into the next stroke. Joel demonstrates both techniques, while Ken highlights the pros and cons of each approach.
