IMO, the book assumes 90 degrees for clarity , brevity reasons in that it assumes one grip type . But Homer does define other grip types and their implications to wrist action. Hence my "smaller" . I personally have the wedges at about 90 degrees , (never measured em) but when writing I didnt want to exclude the stronger Left Hand Grip dudes with their (approaching) Single Wrist Action. Some have Turned their Left Hand all the way to Plane in their grip , at Fix even. IMO these stronger left hand grip types guys do not have their wedges at 90 degrees. But Im open for ideas on this. Also if I may enter the Lab for a moment, even with a more neutral grip in common golf speak there is something else to consider: namely the effect on the nature of the left hand grip and wrist action and the relationship of the two wedges to each other, in degrees if you must , of positioning the ball back in the stance. Lemme explain what Im thinking. We grip the club with the club in its FIX position. Not at low point or where ever . Now for balls played back in the stance , prior to forming the grip, the clubhead moves back along the Arc of Approach. AND THE HANDS MOVE BACK ALONG THEIR THREE DIMENSIONAL PATH TOO . If only slightly . As the left hand moves back , in, up it must Turn slightly. This is all prior to forming the grip. You dont form the grip at low point fix or some arbitrary place and then take the hands and clubhead back to where the ball actuallly is . You dont do this and then ROLL THE LEFT HAND AND GRIP WITH THE GRIP ALREADY FORMED TO SQUARE THE FACE TO THE TARGET . Some people do this , the grip is precision alignment. Which demands precision. You dont form your grip vis a vis some lines on the rubber BTW arent those formed grip things are actually only correct for one ball position? Theoretically. If you subscribe to this turning of the left hand grip, minute though it is ,as the ball placement moves back in the stance, then the wedges are not at 90 degrees to each other anymore and the Hand Action becomes more , er approaches a more Single Actiony action. I think. Please discuss. Mike O . whats your 20? Over. That is to say there is less turning required to get the left hand on plane , less Startup Swivel if you will for the shorter sticks , for balls played back of Straight Away. Add Homer's Grip Rotation into this business and it would make for a nice little thread on how to adjust your machine for specific ball response . This relates to yodas recent post about Plane Line Rotation as (over) reco'd by some Trackman guys. Ive got a buddy who reps Flightscope we're supposed to get together and talk about all this. He's TGM literate so itll be interesting. Maybe Im making some wrong assumptions. I dunno. Im fascinated by the data these guys are looking at and the different ways to adjust the machine or dynamically change the path . This is something we've never really gotten into . Homers ball flight stuff. Its all over the place in the book . What else is new you you say? Itd be nice to pull it together in a thread . Bucket started to but got jumped by a angry mob of visitors. Hopefully times have changed and those guys have gotten bored with us. "And ...... loving it". "Max the cone of silence hasnt worked in three weeks". Happy Holidays LBG.
