if you go to "end"...you come back via "top"...HK describes this as "top arc" and the circle delivery path as an extendsion of this "Top arc" path...there is no axis tilt in a circle delivery path so I presume there is no axis tilt in "top Arc"....there is no early axis tilt to give early straight line delivery path.
Why don't you try and do some straight line thrusting yourself....vary your aiming point....see what shapes you get.... ?? Less gendanken...more ge-do-ing...
Most of the axis tilt in Hogan's swing came later in the downswing.
For your own experiments - you only need to go to shoulder high backswing , you can draw a straight line....don't be scared...do it and post your own stuff....then ask why does it work / not work....BH has never committed to paper of public record that he had an aiming point concept outside his experience of PP3 through the impact interval (as per Coleman video)...It is less than fruitful to interpret his swing through the medium of a concept which he almost certainly did not use consciously. But you on the other hand know all about it....
