Got to say Orange internal routing is a joke and not thought out at all.
I know haters gotta hate, but having just built up my new Hightower, Santa Cruz have it down perfectly for me. Where it’s internal there is no faf (rubber grommet aside) just push in the cable and out it pops, actually easier than external! No cable ties to worry about.
I do like the external brake hose mind as no need to worry about olives, bleeding etc.
