Key on the impact alignments first.
level right wrist, right forearm inline with the shaft from down the line
left arm/club inline face on
Take your grip in that position
Feel your balance in that position
For most folks, if you take some video from down the line, freeze impact.
Now setup with those forearm/hand alignments - use a mirror to check.
Simply put, if you setup in your impact location, it is much easier to get back there
then do some heavy club, eyes closed swings - back and through, back and through - feel your balance.
