The systematic theologies i have
This is a major strand in the Reformed tradition which is my spotlight area of studies. It is indeed useful to broaden the scope, but here i'll just mention the narrow river of Reformed systematics, and not all are rigidly systematic, nor exactly Reformed but Reformed friendly, but there appears to be a difference between this and Biblical theology, which Vos (#13) below was more known for.
