Wow you just described my flybar! My last design was cut about the same length...can't remember exact measurement! However two weights and cf reinforcement. I didn't weight it against stock however I'm sure it's pretty close. The only down fall of the design is still the stop and go however it has never even while inverted caused a blade whack! Damn I really have to order the Xtreme head now as well. Another long wait will ensue....I wish someone in Canada carried these parts......maybe I should open an online store
