I disagree that modern, compact geometry bikes look goofier in big sizes than older designs. First the bigger diameter tubes, BB, and head tube help balance the lengths. Second the top tube slope fools the eye into thinking the effective seat tube is shorter. Third the top tube often intersects the head tube lower than in the past. All told, modern frame design makes bigger frames look more natural than the old time geometry, gas pipe steel constructions did. That spindly fragile appearance is a thing of the past. Just look at the pictures posted by others in this thread to see what I mean.
