Yeah, I was going to say that the best move I made for cleaning up vacuum lines was swapping to fuel injection. People who claim that ECMs are "too complicated" have obviously never torn down a late model Quadrajet or looked under the hood of a mid 80's truck.
I think the best way to set up vacuum lines is with the hard plastic lines and rubber fittings on the ends. With a heat gun you can easily bend that stuff to the routing you want. Then whenever you disconnect a line, it's obvious where it goes back. The hard lines have thinner walls, so they take up less room and routing stays nice and neat.
