IMO the right shoulder initiates a right forearm pickup.
Orr's video on it is really good.
Lot's of opinions on this I hate that neither side can appreciate the other. It's all good with me, whatever style you like, I appreciate both.
There is no opinion, there is no style, only facts. The right forearm has to move 3 dimensionally in accordance to the secondary lever assembly motion on the inclined plane in order to have the clubhead traveling in a consistant orbit. If you set the mass or weight of the clubhead off in an incorrect orbit initially, you will be working against the physics of gyroscopic motion requiring compensation later in the backstroke.
