370% sounds high for TIL, even for a sheetfed process. 360% is the highest I've run across, and 320% is not uncommon.
I'd probably also go for a little less than 100% max K, probably 90%-95%. All of this sounds like a recipe for blocked shadows.
GCR is safer for avoiding color casts based on small ink density variants on press. The tradeoff is that the more black you add, the more you need to watch for the dot gain effects caused by variance in black ink density.
UCR offers the most on-press control, but if your goal is to get things right without press adjustment, and you have concerns about their process control, it could be a risky choice.
