It seems like the right shift cable should pass to the right of the head tube so it stays right and controls the rear derailleur.

Left should pass to left of head tube and control the front derailleur.

My cables cross a bit after coming out of the shifters, but this was the length needed to allow full turns of the bars (though you never really need that and I would like them a bit shorter for a cleaner look, but oh well).

So, should I keep them right shifter/right of head tube & left/left?

What are the pros/cons of the criss-crossing under the downtube. This seems like it would affect shifting performance.
