We use the matsui discharge, but I keep hearing about how great CCI is and some of the premixed sericol's and I will likely be buying those for testing soon. I love the idea of premixed discharge as mixing every time is a pain in the ass. I actually have 6 standard colors that I mix gallons of already and just pour down, activate, and hit with a little water when I use them. The main issue I have with the matsui is how mixing to a pantone can be perfect for some colors and completely off, like multiple shades, for others. There are some weird issues with the pigment separating and changing colors over time as well.
