I have exactly the setup that you are planning on. Keep the Left & Right the same length, it matters. That's just physics. Now people can argue they can't hear the difference but they are talking about their own hearing and not the laws of physics. Of course with that setup you are going to have on the one side a lot more cable to hide (or manage) than the other side.
For this reason alone opt for quality solid core cables that are easier to handle. Your ears will thank you as well with superior sound. Check out DNM's range and pick something you can afford. when looking at their products don't think that the cable's are specific for their amplifiers etc. That certainly true that they are designed in conjunction with everything else but they are tremendous in my setup.
Good luck with this.
