Okay I'm gonna attempt to unravel this thread....

The emulators have low-speed comp damping controlled by a small hole in them, high speed by a spring-loaded valve. The preload on this spring (which Blue refers to) controls high-speed damping. Racetech do different emulator springs for this, but that is getting a bit involved.

Rebound damping is still controlled by the damper rod, and really you need 15-20W oil. Some people even suggest brazing up the tiny rebound hole as the blow-by on the damper rod rings is enough, but I don't think this would give you a balanced fork action.

Don't drill the extra comp damping holes as the instructions say, just open up the existing 2 sets of holes - you'll screw the rebound damping at full compression. If this is already done then don't fret it, it hasn't killed me yet.

Blue, with the greatest respect get some softer fork springs or you will never get anywhere - you've admitted the bizzare settings you're on are a workaround which doesn't seem to be making you happy and you're right the fork springs are too stiff.

I'm with sdusk on the settings really, mine are 20W oil (15W was too litle rebound), either 3 or 4 turns of emulator preload (2 turns was good but it is worth trying it out), sag set as it should be (20-25mm with rider), stock air gap. Mine does slap just a little if you really go bananas but it has a fantastic feel and does what I want it to. I ended up with Progressive springs, linear are supposed to be better, but as a note in case you do the same, they are pretty sensitive to getting the preload right, I only add 3 turns of the adjuster at the front when I add a pillion.

Does any of that help? If anyone's around here or at Rockingham at the end of the month you're welcome to give the axe a try.
