I used Trail Gears Creeper Joint (same concept as a Johnny Joint).
In a year, they are worn to the point that they are noisy, but not noticeably loose if you grab them. I haven't serviced them as much as I should have though...
If I had to do it again, I'd either do stock bushings, or the rod end style bushing which would go right in place of my current joints. Compared to Hiems, they're pretty much maintance free, less vibration/better ride, and cheaper.
