sorry but opinions are going to vary on this subject

In my own personal opinion and in my own experiencethere is no such thing as "the best fallaway" all fallawayswork equally as good provided that they are properly set up.
where the determining factors for me making an arrow rest selection is how well the launchers will cradle the arrow without interferring with the functionality of the rest.

my personal preference is the GKF Infiniti Fallaway because of all the various launcher configurations that is avalable for the rest and the micro adjust features are really a big selling point for me as well not to mention the thing is bullet proof
