I'm surprised you didn't get a response after 50 views from one or two drivers claiming their mfg has the best...LOL. I think if you look at the NCS picture you'll get your answer. You'll find that all the mfgs have drivers making their shocks work. There's probably not one that's any better or any worse than the other. Myself, I have WCM & Pro1 shocks and never have had any major issues with either. I probably rebuild them twice per season at most.
I'm pretty sure most mfgs supply their own shocks. Another source other than a mfg would be J&M (Invader).
