I was also hesitant to fit orange LCA poly bushes to my LR3 due to all the negative comments about them, but I'm glad I gave them a shot and for $150 a complete bargain. It's obviously subjective, but I'm very happy with them. I fitted them myself by drilling out the old bushes with the LCAs still connected to the ball joint. Bit awkward, but doable in a weekend.
I think they do feel slightly different to OEM bushes, in the sense that they don't seem to dampen road surface imperfections quite as well, no doubt due to their stiffness. I-15 here in San Diego is pretty awful, however. The ride doesn't feel any less compliant, though and certainly not stiff or 'crashy', just a bit more 'feel' gets through to the steering wheel. I do have brand new shocks up front and 285/60 r18 tires, so it might feel different for folks running bigger rims. I'd give them 8/10.
