Only rear cross lever on bullhorns I'm newbie.

I have bullhorns with two TT levers.
For safety, I'm considering installing cross lever(s).

I'd like to install only the rear-wheel cross lever since:


Setup will be less clumsy
When my hands are on the handlebar tops, I probably won't be at high speed, as when I'm on the tips of the bullhorns.


What do you think?
Personally, I would install both levers for safety.

No matter how careful you are, eventually you will get in a situation where you need to perform an emergency stop when your hands are on the tops, even if you are travelling relatively slowly. (I have experienced inattentive pedestrians stepping directly into my path only a few feet in front of me.)

In an emergency stop situation you will want to brake with both wheels, and the front wheel provides more braking power than the rear.
