I am quite new to The Golfing Machine and have a question about The Flying Wedges. I have read about it in the book and watched Yoda`s video. But I have a question about what I presume is a drill for practising The Flying Wedges. I remember reading a copy of Southern Golf(a free golfmagazine on the Gulf coast) a few years back where Ron Gring, AI, wrote about a drill I think he called the Flying Wedges (and he described it as a Tylenol Drill since it helpes for everything). You simply adress the ball then pre-set your wrists (left wrist flat, right wrist bent, club paralell to the ground, club paralell to the target line) and then you simply add a little backswing and hit a punch shot. Is this a good drill for the Flying Wedges if practised correctly or are my recollection of the article probably flawed?
