I have the Tom Tomasello 5-day TGM school videos and he clearly demonstrates that it is the left hand that pulls the arrow out of the quiver. The left hand holds the club's grip and pulls longitudinally on the grip as the left hand pulls the "arrow out of the quiver". What causes the left arm to move forward so that it causes the left hand to pull the arrow out of the quiver? In body-swingers, it is the downswing pivot action that pulls the left arm forward (via power accumulator #4). In arm swingers, who use a right arm action (ala Tom Tomasello), it is a right arm throw action that pushes on the PP#1 point and thereby causes the left arm to move forward => left hand pulls on the grip => arrow is pulled out of the quiver by the left hand.
