Why would anyone buy a rebuildable ressy shock if all they needed/wanted/understood was Rancho??? The whole point is to have a shock that can take a beating and be easily repaired!
I think the 6 week rebuild time is some sort of Darwin penalty, since it only takes an hour or two and just as many beers.
I wouldn't expect TREX, KORE, Thuren, Carli, or anyone else to jump if I blew a seal on my Kings or Foxs. They didn't make the seals and they don't know how I abuse them. Its stupid to think they would.
