With the panhard bar there is not a binding concern. The choice between poly or rod-end comes down strictly to stiffness. With that said, I think the poly-poly bar is perfectly acceptable. I would not run the double-rod-end bar on a street car as the noise increase is significant.

Personally, I think the best option for the Panhard is one from Spohn. They make a "combo" type with one poly bushing and one rod end. This is stiffer than the poly-poly, and it stillhas very nice noise blocking becasue of the one poly bushing. BMR doesn't make a combo bar like this.
