If you are talking about me and what I use, then no, I don't base my correct shot line on CTE.
I use different references and visuals for different shots. I am currently experimenting with CTE to decide if I want to add CTE as one of my many references/visuals.
Why do I not use one system or aiming reference ? Because depending on the shot, I find some references and visuals work better than others.
