Logic says that tight circles are going to be worse - but also that the longer the tube is curve is also going to be bad.
The new cables now have no loop simply a curve (does that make sense) - i.e. the cables are shorter than yours so don't need to cross over themselves...
Cables aren't dirt cheap so I would only replace it if you are sure thats the problem.
