Adobe SpeedGrade With Cdng from MLVFS

[reddeercity]

Since I'm a Creative Cloud member I thought I would take a look at speedgrade again , the first time used it back about 1 year ago I couldn't get any good result. Now that MLVFS has two ColorMatrix from adobe embedded , I gave it a go again this time I'm getting better results close to what I can get from ACR/A.E. The biggest problem I had or have is getting the color space correct , I use the Cdng default for the timeline then in the clip tab I Override the input default colorspace with the one I built but it take a very long time and I still needed to add a Lut, used "Blue Ice - SL - 3527" . There is still some issue with high lights, can't seem to get the right raw color space .

Used a linear colorspace Curve, had to pump up the blacklevel in the Hi(.015),mid(.009),Lows (.014) .
Exposure ,Hi(6.5) Mid(8.5) Low(8.6)
Raw White Balance : Red-1 , Green1-1.017 , Green2-1.021 , Blue-0.882
Matrix: Hi-1.251- +R.083 +G-0.097 +B-0.005
Matrix: Mid-  -0.23 +R0.516 +G-0.014 +B0.011
Matrix: Low- 0.173 +R-0.009 +G0.931 +B-0.031

I wonder if there is anyone who has good success with Cdng's from ML in speedgrade and if so how did you achieve the right raw color space ?
Or is there anyone who uses speedgrade on a regular basis, that has any tips to share , thanks.
