I am using the alum saver top and the 2.0 set up It is set a little looser than the 1.0 but I agree that it is a personal driving technique thing. Some drivers like it loose and others like it tight. I use to tighten the 1.0 all the way down and every weekend I would blow up the plastic lower piece, after a season of having it set too tight I even blew up the top bearing in a JR9100T. That is too tight. Through trial and error I have found that I like it tight enough so the servo holds the wheels where I point them, but not to tight that it cant do its job. I put it together and then with the radio on try to make the saver work by moving the wheels with my hand by trial and error I know when it is right. Just play with the saver and you will find the right setting.
