[Martee]

Sigh...you missed my point regarding the Impact/Low Point Plane Line discussion Martee! I'll leave it to Philly to clear up the mess!

By the way, Thrust is always Cross Line (think Right Forearm Angle of Approach and Aiming Point), even for the Swinger. However, Delivery Motion is On Line. Please tell me I haven't opened another can of worms

Sorry I missed you point, but either my reading or your writing led me to my response.

As for you last statement, I didn't question the application of thrust crossline, I question that the description by itself leads to bent plane lines when a golfer reads crossline. Okay they don't understand the concept, actually the lack a good understanding of the geometry of golf stroke.

Golfers don't bend plane lines cause they think they should, they bend them cause they have been told too or they think they have been told too by some other action in the golf stroke.
