This is my summing chain:

1. RME ADI x2 (16ch) / Big Ben / Rme HDSP 9652
2. Allen&Heath GL2200
3. Mindprint DTC
4. Fatso
5. RME ADI 8
6. DAW

Think the EQ and comp is solid on the DTC

I use the Fatso for compression and warmth - tranny etc. I'm very happy with my setup. I have no tips - think the comp/lim is pretty straight forward to use, no issues.
