Not sure if hes using the 10-20-c trigger but he definitely cocks his wrists and rolls through impact and he has a late release. He might not feel he does as all hes feeling is a pivot controlled swing but he does.
Reminds me of Moe starting from that preset address position. He has to cock and turn his wrist to get into that address posititon.
Surely this aid is teaching him to maintain the lag and to have a FLW as he has no need to flip to get the red ball aligned with the real ball. Takes the focus away from the clubhead. ?
