Default KYB SSS Valving Input Please

I put a full 2008 YZ450 Front end on my 2000 GasGas XC300. I am 51yrs old, (riding 42 yrs). 6' 4", 250lbs in street clothes.*I enjoy all kinds of riding but prefer difficult single track, trails and hills.*(probably*B-C Enduro). *
*
I changed springs to Racetech 48 with 5mm of preload.* I have tried to soften the forks about 7 times so far and below is what I have now for a tune.

The forks are still too stiff on trail trash even with the compression adjusters complete loose. They work great for big hits but they are too stiff most for most all else.

It seems that the compression screws do not have a big impact on the dampening.* Any input would be appreciated.
