I don't have any links other than to other threads on here when I've brought it up, but I'll try to summarize the theoretical basis.
Romance styles, as Gulenko defined them, are nothing more than a manifestation or characteristic of the ego block, in particular the irrational element in the ego block. Thus the same analysis that applies when comparing any other characteristic(s) of a particular block of Model A also applies equally to romance styles. As such, you cannot consider the ego block in isolation. There is no reason to doubt that a romance style would also not manifest from the super-ego block's irrational element.
With respect to information metabolism, there is a major divide between static elements and dynamic elements: they'll either be in the mental block or the vital block. As such, competition will never be between a dynamic and static element; however, the two static irrational elements are always in competition: the more the person uses one, the less the person uses the other; so whenever you are examining a manifestation of the ego block, you have to also consider the competing super-ego block. Now, it's a given that the ego is the dominant and preferred information metabolism pathway, which is why the ego block's irrational element constitutes the primary romance style. In certain situations however, the super-ego block's romance style can also manifest--this depends on a number of factors. One's secondary romance style will have a more significant role the stronger the person's rational subtype is, and vise versa, the secondary romance style will play a more minimal role the stronger the person's irrational subtype is.
Statics will always be a combination of aggressor and infantile; dynamics will always be a combination of victim and caregiver. Here's a link to a crude illustration of this I made a long time ago, ignore the big circle on the left and just look at the two smaller circles on the right:
