For a tournament, how are stabilizers measured? From front of riser or where. Reason I ask, I have a archer's advandage, then a quick release attachment, then my stabilizer. Am I limited to 12" total if shooting hunters class? Also, can I shoot that class with the legs of my archers advantage installed. Makes it nice cause I can stand bow up after the shot, without having to put them on each time. Thanks for the help?
