I'm not Mark Coma, but I ain't no slouch and I certainly find the rev limiter when space allows it. The only real drawback I have seen to more plush is the inability to take big hits ie. 20 foot drops at 60mph. I don't take my bike to the track much and prefer the challenge of terrain I don't know and can't control.

Has the suspension worked for me and how I ride? Absolutely. Would I recommend Pro-Action? Yes, but not to someone looking for an enduro setup. If anyone wants to feel what a LOT of plush is like and weighs near what I weight (160-170 without gear) feel free to ride my bike when the roads are dry AFTER I get back from Baja in January, lol!

I disagree on your opinions on fluid though... In a straight shock/non valved system, yes, fluid weight is key to mastering bound, rebound and damping. In valved systems shimmed and sprung for a specific weight oil weight is pretty much set in stone. To vary parameters I would try 5ml more or less than the amount in the shock before I changed the weight of the oil.
By dirt bike I meant my bush bike. KTM 250XC. I ride mostly bush here but come spring and fall I do 1-1.5 hour motos at Wild Rose to keep in shape. Fill gas, run till empty. My suspension will do both quite well. As stated I like it on the firm, reactive side. There's so much feedback in suspension I hate to lose that. On my XRR (agressive dual sport), I went softer and it's somewhat "go with the flow" on the single track. Floats over rough stuff, but feeling and responsiveness is definitely lacking. It's a decision on what people want. A sloppy couch is comforting to sit down over the rough stuff, but is sitting what you should, or want to be doing?

How do you raise or lower fluid level in your shock? Did you mean your forks? Shocks have purged air..

Valving is not just that. Set in stone. Viscocity changes. Moreso with thicker fluids. Hence why I said a thin oil keeps more consistant viscosity over temp ranges. I notice all the time when I jump on a bike the suspension isn't nearly as good as after 15min -1/2 hour of hamering on it. Even a trail stop cools the oil enough for me to notice it once we get rolling again. I've learnt to roll into it slowly because of this. Most accidents happen after trail stops. I firmly believe this plays a part, along with being sloppy and having lost flow.

Both shocks and forks have valving... That valving controls the rebound/compression. By changing viscosity in the oil with temperature it changes the valving resistance. When forcing oil through small shim stacks and holes, it gets hot quick.

I can see having a softer, heavier bike would be comforting, but it may not be what everybody wants.
