Sorry Dave, but I wouldn't count on this being a true statement. I suspect you will definately be unhappy if you get the wrong version counterweight installed. The difference between rotors is generally not much, and you're allowed to have rotors that are something like 3 letter codes apart without balancing. I don't think having the right series counterweight is optional though. Rusty Can someone translate all these buzzwords and explain how they relate to one another? S4, S5, S6, letter codes on rotors, etc??? Thanks, Bill Bradburry
