Thanks for the explanation, LDICesare. It helps a lot to understand.
What I do not understand is what you say about the width. It is known that it's easier to read a narrow column then a wide one. (that's why newspapers publish in columns). Reading wide lines is very unpleasant. Still many of you claim that the wide style is better. Can you explain that?
The Astygmat thing may explain why it works good for me and not for you. It's indeed a good reason in itself to offer an alternate style.
