I'm doing Powerflex ones, have them sitting in the back of the truck as I write this. I have them in my E39 wagon and they made a huge difference in driveability with no noticable increase in NVH.

I'm doing the lower control arm bushings as well from Powerflex as I think one of them is slightly mangled from a previous accident. Have to get in there and replace all the upper arms on that side (already did the passenger side arms) and do balljoints as well. As previously stated I want to go in there once and forget about it for another 8 years. The truck sees 10-15k miles a year at this point so its gotta be reliable.
