People with Poly/Rod end LCA

I am planning on buying these and I always thought/read that you put the rod end on the axle and the poly end on the body. But I just read this on this web site http://home.columbus.rr.com/trackbirdz28/toppage1.htm

"The poly should go on the rear axle, as the axle moves vertically (only on one side, like hitting a pothole) the control arms must swing in a slight arc (not just vertically). This requires the rod ends to be on the body to allow the axle to rotate without binding"

Can someone confirm this for me. I am very confused

I run the poly bushings on the body and the rod ends at the axle and there's no trouble that I'm aware of. And, IIRC, this is what Spohn Performance used to recommend to keep down road noise.

However, Gobal West does recommend placing the poly bushing at the axle end. They don't go into any detailed explanation as to why though. Still, I'd follow GW's adivce.

I did try e-mailing Global West, but their address bounces back with a permanent fatal error.

At some point, I'll probably go full rod end, but not until I stop driving the car everyday.
