Thought I would add this as I have come across a number of students and teachers that state....."It's my way or the highway and every other golf swing method or swing technique is wrong and incorrect.....my swing method is the ONLY way a golfer will be successful" .
That kind of thinking is total BS and I shrink away from any golf swing that states that. To many know it alls in the golf teaching profession IMO. It's proven by watching various highly skilled pro's or low hdcp. golfers from 15 to 85 that any kind of swing can work for an individual.
IMO you build a swing that works for an individual. Just as you custom fit and build golf equipment around an individual golfer and their swing. Golf swings and golf equipment are not "one size fits all" that many profess.
My rant for the day.
