I am on the fence about proactively replacing mine - the indy shop recommended the poly bushings to avoid frequent replacement of the oil-filled ones when I first bought it, so I did that not knowing any better. I'm due an alignment, so perhaps I bite the bullet and swap to the Meyle HD, or just swap to the stock ones and just do the FCPEuro warranty when they let go. Having a catastrophic failure on a trail would suck.
I'm like you. The control arms I bought to replace the Luck8 turds were the ones Atlantic British sold with the green poly. I almost immediately regretted it as the ride was noticeably more harsh. I think I'll swap them for the Meyle HD version soon.
