When you hit and go "in a straight" line. Is that more of a feel or is it true geometry? What I understand has a swinger and hitter the same geometry..
The only thing I know that can move in a straight line is our "clamps" from startdown into downstroke, or?
Arc of approach and angle of approach. Curve or straight line between impact and LP. Does the clubhead really draw a straight line...? If so, whats the difference to a flat spot???

I´m really confused here...
Another but simular

question:
I understand as a hitter you can trace the planeline/baseline OR you can trace another line, if so what line is that and doesn´t that mean that you´re bending the original planeline? I know that there is a line that Mr Kelley named the alternate target line. If you cover that line, isn´t that the same as tracing the baseline?
I am sorry for this very foggy thread in english/swedish....
Maby someone can help me back to the path
Thank you!
