Going slightly off topic here, but what the heck.

You can also use Bungie Cord to visualise the Straight Line Delivery Path of the Hands going downplane on the Downstroke.

Just have one end of the cord under your left toe (or better still, tucked under somewhere where the ball would be) and stretch until your hands are Right Shoulder high which is the Top location. Then just take your Hands down that straight line path all the way down! Your Right Shoulder should also go down that exact same line.
