[O.B.Left]

Is it just me or does Brian look a tad laid off there at Top? Dont think Ive seen that in any of his recent swings. Ever so slightly arched?

Any who both those guys get on their Impact Plane Angles really early .......the sooner the better to my mind. Both have a very minimal shift from Top to get down there too......also a very good thing to my mind.

In the first frame Brian is TSP'n it , in the second frame he's TSP and has dropped down to his Impact Plane Angle so he has shifted if ever so slightly during Startdown. Double shift but very minimal in terms of degrees ......something I think makes good sense if shifting is hazardous.

Lovemark's Rotated but doesnt shift much either. I say Rotated but if he Slides and Tilts his Axis it wont be Rotated by definition anymore. Not sure if he does that or not. If he does it Rotated/Down combo maybe even though its not actually planed like Bucket says? Still dont have my book with me to look up the proper terminology.

Anyways in regard to this posts initial question: Look at Brian Gays first frame there. Since we're talking Homer and Lynn around here assume he wants a TSP angle at Top. (And I do have to state a preference for them personally) He's got himself on one there nicely, fairly close to his Impact Plane Angle which D has drawn for us right? Not much of a shift required therefore.

Now imagine him making a steeper turn of the shoulders in Startup.......in doing so he'll find a TSP angle which is further away from the Impact Plane Angle , the red line there....... Requiring a bigger shift on the way down in terms of degrees. Bigger shift bigger hazard. Thats my final answer on Flat back, why?

Im interested in other opinions .......Rotated , Right Shoulder above Plane .....interesting stuff.
