Got cha. I'm sorry Matthew I really didn't say what I meant in that post. I meant to say that the left and right shoulders look as if they are on the same plane at impact.

Thanks

Thats cool

If you observe Hunters stickman drawing at low point here - you can see that they are on a parallel angle as the plane yet still above the plane. This parallel above the plane is a reasonable approximation at this point for the dimensions of this stickman diagram (and in real life the center I think would be further above plane).. because the right shoulder and the left are in the transition of swapping over as to say...

Note that again the shoulder flexability will be stretched by extensor action towards the plane line - and not being stretched directly backwards. As an analogy, if those shoulders where a bow and the arms the string - the shoulders would not be pulled backwards (or forwards ...lol) so that they would touch the inclined plane....
