Rubber or Poly for a Daily Driven Corner Carving Street Machine?

I put the Hotchkis greasable LCA pins and poly bushings in my Duster and had a hard time noticing any difference in the ride quality except on terrible roads where the ride was already bad anyway. However not having the extra flexibility of the rubber bushing makes the strut rod length much more critical; I noticed after a few hundred miles the LCA slid back on the pins just enough to see a space and I will be installing adjustable strut rods ASAP as I have an odd clunk and sometimes my steering feels funky when making tight turns (also need to replace idler and maybe pitman arm). I think most of the folks here who had not-so-good experience with the poly bushings simply swapped them in place of the rubber and didn't change anything else; like 72BluNBlu said you really need to change out the bushings, pins, and strut rods all at once or you will have problems.

And for the record even with 1" T-bars and the poly bushings my Duster rides like a silk carpet on a still lake compared to your typical modern mid-size or smaller car which like to transfer every single little road imperfection to the chassis. I guess it's good for control and steering feel but I drive a lot of 2015-2016 model year rental cars for my job and they all ride like sh*t in comparison (I've driven Kias/Hyundais which are the WORST by far, Nissans, Toyotas, Fords etc.).
