I'm a ex automotive race tech, and now I work in hydraulic engineering, so this has been a fun project, my biggest problem is time to test. I do most my testing twice a month at events, so it's not ideal. But like I say, It's all about fun.

I have two last things I would like to improve on, first is the high speed damping is a little harsh, and second is the my comp adjuster is nearly all the way out.

I'm going to replace the 2.25 pivot shim at the base of the stack, I think (and i'm hoping) that this will improve both of my issues.

Don't ignore the mid-valve...a lot of magic can be massaged out of it
I set the float at 1.5 mm but also used a light (10) face shim.
And while your at it, think about the rebound stack... I had to stiffen up mine quite a bit to cancel out the pogo effect.
I need to go even stiffer on the fork's H/S reb

Where are you measuring you 1.5mm float on your mid valve?
The .10mm face shim makes sense, I may try that

Yes,
between the piston face and the first shim or face shim...I used a feeler gauge and guesstimated as close to 1.5mm as I could without any deflection of the shim.
I trail only, logs, roots, rocks, all woods and jungle stuff...no mx.
That's why I can get away with a softer valving setting.
Did I mention I did go to stiffer springs front and rear, so that I can get the bike to ride higher in the stroke.
