I have some Triomphe levers that are switchable between aero/non aero routing. I would think you get more pull with aero routing compared to non aero. It's more of a straight shot from the cable hole in the brake lever body to the barrel in the lever. Just my thoughts but what do I know?
I have modern Tektro levers on two of my bikes and like them and more comfortable then vintage levers but they're also very bulky looking. So if your not going for matching style points and just want something that feels good and works go with Tektros. Plus they're cheap also.
