Sprocket - How to mark SLR systems?

Working on a bike app and wondering what the right way to mark Shimano SLR/Super-SLR components is:

I often see catalog descriptions like "Brakeset: Shimano Ultegra Super SLR w/ aero levers"

So do you expect or does it make more technical sense to see SLR on the brakes part, on the brake levers part or on both? I know theres a physical spring added to the levers, but ive seen the SLR 'markings' on brake caliper quick-releases..

A:
Brakes: Shimano Ultegra SLR
Brake Levers: Shimano Ultegra

B:
Brakes: Shimano Ultegra
Brake Levers: Shimano Ultegra SLR

C:
Brakes: Shimano Ultegra SLR
Brake Levers: Shimano Ultegra SLR

Thanks

SLR added a spring to the lever and reduced force of the spring at the caliper. SLR was introduced on single pivots, Super SLR with dual pivots. And now a days New Super SLR and SLR EV being the new system. They all have different pull ratios.

I had tried to use SLR 6400 series brakes with some old Superbe brake levers- the brakes didn't have enough return force to push the cable to push the levers back to the "start" position.

That return spring in the SLR levers performs that function.

SLR = Shimano Linear Response. They put a return spring into the brake lever and lightened the force exerted by the spring in the then single pivot brake caliper. That made for a "lighter" feel at the brake lever.

Cheers
