Ends for suspension links?

[rixtrix1]

Has, or does, anyone used ends such as Suicide Doors Super Pivot Joints, Rustys Offroad, Flex Joints, or Currie Ent. Johnny Joints instead of heims in 3 or 4 link arms? Seems to me the greasable joints with delrin races would be much quieter, better lubricated and easier to maintain than using heims, poly or delrin bushings. The much larger OD could present some packaging problems though, especially with a 3 link. Just a thought.
