First, onplane means from the down the line view not the face on view...
Secondly, for someone starting at adjusted address (that is the classic, mid body hands address position, usually with a bent left wrist and relatively flat right wrist), the flying wedges are not set up - they are set during the swing when the right wrist bends (to the point it will be bent at at impact)...
Thirdly, to get the right forearm on plane at address, you need pretty high hands...
Chris,
Your reply post to Teach above containing the quoted excertps was sensational. Thanks!
