This video clip demonstrates a slow, long stroke combining forearm action with some upper-arm swing.
It is a useful way to integrate the lower and upper half strokes.
Détaché in the middle is also commonly used for fast détaché. In this case only the forearm is active and the upper arm, hand and fingers are passive, just balancing and reacting to the forearm action.
Notice that Fintan's right elbow moves freely....
