You figure as someone who specializes in tuning he would being trying to help people out. And any decent tuner knows that if you are struggling with your fork the issues are likely related to spring rate or rebound. Compression is litterly the last dial you turn.
Dougal's first message here is asking OP if what the issue OP has feels like one issue he is aware of, concerning OP's fork's model. I call that "being trying to help people out". He may deviate from topic and post weird messages but You can't deny he is trying to be helpful.
Any decent tuner will first check user's suspension model to see if there is any obvious known issue with it. As Dougal dynoed the same damper and found issues, one of which corresponding to OP's symptoms, there is nothing wrong pointing to that particular issue.
If someone tell me their moco sucks or that their deluxe select lacks sensitivity and support, I won't tell them to try other settings. I'd tell them to get rid of that POS moco and get some french tech in there, or I'd probably fiddle with those several thick plates hiding the deluxe's piston for some reason. I won't try to turn any dial on that marzo DJ I just bought before going to the lathe first for the same reason.
Compression is the first dial you need to turn if it act as a lockout... that is obvious I hope... But if the compression setting suck as much as a lockout, you need to take care of it first.
And last thing,if you think modern suspensions are all equally good, you probably never try a good suspension. When I had a Crconception damper, It was fast, I was never tired, never had painful fingers, and I could use any spring rate from RS except the hardest one,
and turn the knobs in any position. It just worked. It just made the bike from "good" to "awesome". That is what I expect from a suspension before thinking it's good.
