The left wrist uncocking provides the 'down' and the pivot provides the 'out'. Uncock then roll. The 'roll' is imparted by the pivot. The combination of those two force vectors = 'on plane' sweet spot. Force moving away from 'center' to its in line condition, which is separate from the in line condition of the lever (left arm and club) IMO.
Yes, the throw out action is the 'cracking whip' moving through the body and down the 'lever' of the left arm to its 'straight' position - that 'force' is 'in line' at both arms straight. CF is 'driving that whip'. The flywheel.
Send 'force' to both arms straight, in front of the ball and you can not have throw away. You will also have 'support' at impact. Resistence to impact deceleration. Mass in your lever.
