Stupid question: Poly bushings on the front

[derekf]

Ok, yeah, it's a stupid question and I should know better:

It's known that poly on the rear control arms (on A-bodies) is not a good plan because the rear end needs to twist and with poly it binds up.

What about on the fronts - I can't think of any reason why poly (or other low-deflection material) wouldn't be just fine on the fronts as the bushings shouldn't need the ability to twist. Is there indeed any reason (other than NVH) not to run something stiff on the front?
