Equalizer vs Dual Cam

Of course there is some friction involved because of the force imparted on the cams by the spring bar, but the way I see it, the crooks on the bars "roll" up and down on the cams in relation to swaying.---

The sloped surfaces on a bar don't "roll", they slide. It's two metal surfaces being forced together and that generates a friction force.

If the non-rolling cam could be replaced with a roller bearing and still generate the same amount of "sway control", I'm guessing the Dual Cam would be made with roller bearings.

That would eliminate the noise and wear which some people find objectionable.

Is there factual engineering info. from the manufacturer that supports the claims here? Just being curious.

None that I'm aware of. If I knew of any, you can bet I would cite it in support of the claims I've made.
