This is the classical case of people thinking the world is split into PURE One plane swing or two plane swing (hybrid planer

too funny).Hitter or swinging in TGM. "they must posses a special trait , move or component to be pure"
'in TGM Pure Hitter or Pure swinger and must follow 24 component set out by TGM', that is not the intention of TGM, TGM is a catalogue with a guildline. Hitter and swinger are are mechanical actions. Either using Centrifugal throwout, Or muscular drive and it cannot be both since Accumulator 1 replaces the centrifugal throwout. Safe to say, Accumulator 1 = the muscular drive in ALL HITTER.
There are more hitters in the tour imaginable because its easier to control the hinge action with hitting. And its more powerful ( my opinion) for stronger people. And players are Stronger than ever.
Sequential release ( NOT tom watson, colin Mog.), SNAP release(NOT tom watson /jack), Horizontal hinge ( NOT Colin, Hogan, Bobby Clampet ), lagging takeaway( macogrady the hitter use that) , long backswing ,RHYTHM, TEMPO(Hogan and Sergio and Ochoa swing HARD , Stuart appleby the hitter look smooth and easy) are not limited to swingers nor exclusive ..
I simply stop thinking that the Hitting and swinging patterns set out in TGM chapter 12 are the "best" and "ideal" in the golfdom, the book will be as thin as the plane truth for golf if it is, because he would not have to catalogue it and gave us CHOICES. Its just a guildline what Homer Kelly thinks is a start, l would give him a PM if he is still alive. But Homer Kelly said it, He didn't care what we do, as long as we understands why we do it for.
People just love to see black and white, absolute, stereotype.
