Rubber or Poly for a Daily Driven Corner Carving Street Machine?

I haven't had any issues with the poly LCA bushings I've installed. I also installed them with greaseable LCA pins though, because the poly bushings can squeak if they dry out. Not an issue with a greaseable pin though.

Were I going to do another set though I would probably by the Delrin LCA bushings that Peter Bergman sells. More durable than the poly, and even less deflection.
