So about a week or so ago the drivers side thrust arm bushing on my X5 blew out its fluid, thus causing the shake when braking etc. we all know about with the thrust arm bushings. Seeing everyone who went with polyurethane bushings almost immediately post a thread trying to isolate the new shimmy they have and say it feels kinda rough over bumps now comparatively, I decided to go with the Meyle heavy duty bushings which are the same design as OEM, but solid rubber vs the fluid filled. I can say these are stiffer and more sporty feeling than the OEM design, feel more connection to the road... but without the overly harsh feel of the solid polyurethane bushings.
So for a quick basic guide for those looking at thrust arm bushing options, here it is.
OEM bushings: Softer more comfortable feel, wear out from 20k miles to 40k miles on average depending on where and how you drive.
Meyle HD bushings: more solid and sporty feel than OEM while lasting longer, and won't cause you to feel every shake,bump and shimmy on the road. Good balance of performance and comfort. (like M3 control arm bushings vs series bushings with E36 and E46 platforms)
Solid polyurethane bushings: Track car performance but not the best for city driving. If you live somewhere where the roads are long, smooth and winding these would be great, but in city driving may be too rough for you.
And here's the link I bought mine from. (thanks FSETH!)

If one of the forums great sponsors starts carrying them they should tell start a thread as this is a good product that I feel makes more sense than the polyurethane option, while less known of.
