[ROVERNET - UK] Bushy question

[Alan Gale]

I need to overhaul all rear bushes on my 3500S and am confused about the 
debate between rubber and new softer urethane bushes.
Scott's here in Melb can supply me with softer urethane, but I have not been 
able to source an alternative, and am wondering if the doubts I am hearing are 
well founded or overly nervous.
Is there a good source of standard bushes, and if so where and at what cost?
