true ya man i run almost the same setup but im using derailers wires with linear housing and a y upper cable that has an issue with having way to much friction even for a y cable
you should try the dual london mod setup you bolt on the secound one to your cable guide and run your houseing throught it works really well and looks clean
ya i know but you can drill it out to fit and as said im prolly getting a new lever soon anyways i was think about going for the m2 comes with the oddesy dual upper cable
