I'm an avid Mag user and love the Kompressa, but I can't use the two together. Try it for yourself,  shooting a kompressa into a mag bubble... instead of the globs going into the center, they fly wildly out in a single direction. The only way to use kompressa with mag is by standing on the opposite side of where the globs fly to so that they stick to whatever is in the bubble first. I can't seem to figure out what determines the direction they fly in either. Super strange.
