I am looking for a little clarification on the role of extensor action with regards to putting. How does one go about using extensor action when you utilize a FLW equivalent? Typically most people do not putt with the primary lever visually straight from fulcrum to the sweetspot. Doesn't extensor action provide the force neccessary to keep the left arm extended without muscular tension? How do you use extensor action when the left arm is bent?

I've been searching the archives on this one but have not found specific reference.
