Good Afternoon.  My handicap index has gone from 14 to 19 in little over a year due to poor ball-striking (coming over the top).  I saw a video from Monte Scheinblum on the internet called the No Turn Cast drill.  It incorporates 2 things I do very well, not turning and casting the club :-). I have used the drill on the driving range twice and it appears to have drastically improved my ball-striking.  I have not yet taken it to the golf course.  Has anyone tried this drill and used it in play?  Thanks for your thoughts!
