So, if I understand correctly, there is no clear advantage in the performance department. Just more of an issue as to what levers would be used in conjunction with what handle bar set up.

If I want to go with drops or trekking bars, then canti's and either aeros or non aeros would work.

If going the V Brake route, I'd be restricted to MTB levers and upright type bars.

To use the V brakes, I'd need a "travel agent" to get the correct travel ratio, correct?
