I recommend adding Cane-Creek hoods and keeping the auxilliary levers.
Careful trimming of the hoods, and adding a thin spacer-washer as needed, can make for a robust installation.
This allows comfortable braking from a more-aggressively set up rider cockpit, i.e. with a more-foreward rider position, still with safe braking when riding atop the bars in rest/recovery or downhill mode.
It also greatly expands any road bike's off-road potential when it comes to safe descending on steep trails.

Auxiliary levers together with hoods are compatible with tradional (non-aero) Mafac, Weinmann/DiaCompe and even some Dura-Ace levers!

For restoring the original amount of lever travel that some aux levers take away from, you can just trim a few millimeters off of the front-most part of the lever body, the flat edge where the lever(s) smack into when you release your grip on either brake lever.

Some of the Weinmann/DiaCompe aux-lever-equipped lever bodies were even trimmed this way at the factory, restoring the full lever throw travel and thus dismissing the need for calling aux levers "suicide levers".

Good setup, cabling and brake pads go a long way to giving aux levers more power than you can use.

I have come to like the look, what do you say?
