N1: Good point. Instead of the engine lot had so far focused on implementation. Even the Potomac reference is historical and things may have evolved over time. But I wouldn't know being CFM dependent.
To bite one's lip, A319 with IAE looks way too cool, one of my favourites. Somewhat scary, think 262. Steed of the breed, imagewise.
