Riding in the Central Park tonight, I suddenly realized that I am switching from and to aero position way too often. It all has to do with being forced to reach for the brakes to adjust my speed (I am afraid of running over squirels and pedestrians). So, I decided to buy a pair of cycloross levers and run cables up and down my aero extensions - this will probably add some 100 gramms to my bike but will make the ride way safer and (probably) faster too. So far, all I was able to find was that some pros (http://www.velonews.com/tech/report/...es/8100.0.html) are doing it too, which gives it a bit more credibility. Has anyone done it, any specific products, problems, thoughts?

PS. upon looking a bit more, I found a Hed product designed to do exactly that - it's called "the third lever" http://www.hedcycling.com/aerobars/thirdbrake.php and is kinda sleek, but (a) rather expensive and also does not look too comfortable.
