I recently switched to bullhorns and have a cross lever near the stem. After about 1000 miles on this setup, I'd rather have the TT lever at the end of the bars. When I'm going fast downhill or grinding hard, I am on the bar ends. That's when it would be nice to have the quickest access to brakes. I am either going to switch out levers or try to run an inline setup so I have brake levers in both hand positions.
