I'm not quite sure what jointed arms are, I'll have to look up those other systems you mentioned. I chose to run the rubber bushing on the body ends of the link arms and the heims on the rear end side. Its not as quiet as rubber bushings all the way around, but the noise is very slight and only heard at parking lot speeds going over bumps.
