Gracias, rodar y rodar.
I like it best when I can take out the bottom bracket and run the cable in through the top of the down tube and out near the end of the chainstay (less drilling is a plus) The BB bypass works well, too, though.
Recently with the darkness of winter, I have been thinking of excuses to use reflective tape. Using it to hold a cable/wire in place would give a functional purpose beyond being a reflector.
