The Sram Carbon TT brake lever is a good looking and lightweight lever that performs flawlessly.  The thin carbon lever does not cut into your hand like some others with a similar design.  Moreover, the lever feels very strong when braking as it does not wiggle or bend.  You simply squeeze it and it applies the brakes just like you expect it to.  Then it immediately returns to the open position and is ready to be used again.  If I had to quibble about any aspect other than the steep price, it is that you must use a significant amount of force to tighten the bolt enough to prevent the lever from moving inside the bar.
