I'll start with the experience, pro bike supply was nothing but professional and responsible. Buy a thing, it gets to you and everything is on the up and up.
The product itself, is an interesting set of compromises which are less easily tuned compared to any comparable air system. It is not clear to me that small bump sensitivity/shock performance are actually better over longer DH/Enduro runs.
Multiple test runs on Windmill, a 9 min. (If you are very fast) descent at Wind rock, I could not tell you which performed more consistently but I can for sure tell you the air shock was more effective at changing ride feel and fine tuning.
I'll leave you with this, the air shock and coil both did the jobs well enough. The weight on the coil is significant but the service lifecycle of the air shock is also significant. If I wanted something to service irregularly go coil.
