We use the Epic PC system. Amazing Base for WOW printing. We mix nearly everything in house with the PC system, including our own standard spot colors. Still, I would prefer to just order "bright red" by the 5 gal than mix it. It's just that in the case of WFX, the spot colors they sell are sold at a higher price than our cost to mix. However we are buying gallons of PC and 5s of base. Quarts of PC and single gallons of base are very expensive (and hard to come by in the case of PC quarts) by comparison but with two autos you shouldn't worry about that. You will have a lot more inventory value on the shelf with the PC systems, some of the PC gallons are well over $300 per.
If your crew can follow directions and use the IMS the PC system is the way to go. If you have a concern that someone might ignore the flashing red hand and warning symbol in the IMS when a mix is off and stick that ink on press then go with Equalizers. With the PCs you have the greatest control and you can tint Performance and Top Score bases which cannot be done with Equalizers. If you do enough performance wear printing that alone could make it worth your while. I recommend Nazdar or TechSupport SPS for vendors.
So if you were currently purchasing stock spot colors from Wilflex then yes, the PC system would save you money for the same ink. (with the exception of Wilfex super opaque fluoros which are dry flake mixed and not repeatable from any of their mix systems) I believe QCM is more affordable than WFX for stock colors....heck anybody is prob more affordable than WFX for stock inks. In that case maybe pull the WFX mix system in to mix your pantone matches and customs and keep running with the QCM spots. The QCM WOW inks were always awesome when we used them back in the day, if they still are, and the price is good I wouldn't see a need to change those. Like Colin said, it could be very difficult to match them as well.
