Mine are set up like Arctic Hawk and I have no problems. The bars shape (I have the same bar shape) allows for a clean exit such that when I am holding the drops I can feel the cables in my hands where it seems they should be. When holding the middle drops the cable may touch the underside of my hand but mostly it's clear. So the shape of those bars may be conducive to bar end routing.
I am curious about the set up fixer has. Do those shift fast and smooth? One good thing about routing the way arctic and I do is that you can redo your cables without removing the tape. A reall muddy cross race can destroy your cables.
