Well, stacking modules are supposed to take something that’s already present in a major sub and emphasize it, make it stronger. Until the multi-stages, Emperor was the all-in-one solution.
I do like your idea of using the stacking modules more like superchargers and running them when the situation calls for it. In that case, you will probably find that it takes a while for your mind to realize that’s what you’re doing, so at first you’ll notice little difference, but at some point you’ll start noticing it.
Also, start running them at least one cycle before you start the activity, like how you would eat something a little bit before an activity that required the energy to give your body some time to metabolize the energy.
Take some time to figure out how Sanguine makes you feel. I believe many report it makes them quite Zen-like, so you may do that around meditation or even socialization.
