I just realized something watching your video & thanks to the Durock stabs being slightly translucent. The inside of the stabilizer stem where the wire goes has a sharp angle in it where it turns to allow for the end of the wire to move up. I wonder if stabs were produced with a gentle slope there instead of a hard angle whether it would make any difference to rattle or not? Anyways just a thought, the new lube looks promising for dampening the wire! Gonna have to grab some & experiment myself.
