Most recent setup: Planet X Brakes, Swiss Stop Yellow and Reynolds DV46 tubular
Other experiences: Campag Athena with Campy Aluminum Wheels
Overall, with the Black Prince pads, I'd be hard pressed to tell the difference in performance between the Planet X setup and this. Modulation is good and power has never left me feeling concerned about being able to stop. In other words, they are powerful enough for emergency stops during Cat 4 and 5 crits and tightly formed packs in road races.
The brakes came with zero instructions and completely disassembled with several shims. It took me awhile to figure out that they were shims and their purpose (the pad holders are very low profile so additional shims are necessary).
The rear brake backing was larger than my brake bridge, so I had to recycle a washer from the planet x brakes.
Last complaint is that I had to really crank down on the tensioner to prevent the cable from slipping. I feel that I exceeded whatever recommended torque specs that would have been stated had instructions been available. This could be the Alligator cables. They do seem to not want to stay put.
On the plus side, centering these with the Alligator cables is very easy. Not sure how they would fare with super stiff housing like my old Yokozunas.
The brakes look gorgeous, much better than the pictures. Weight with minimal amount of shims and pad holders was 139 grams. Complete set with 18g of Zipp cork pads was 159g. Weight with Swiss Stop Black Prince Pads (highly recommended) is 174g.
Only gripe I have about them is that I'm running them with 404's and I can't set them as loose as I normally like them.
The clicking may have to do with the wheel pulsing (not sure if the wheel actually is pulsing, but my front was for a little while)
If its a carbon brake surface it could be some brake pad burnt onto the rim. Good clean with brake cleaner will fix it.
Sounds like your Gravitas could do with some lube

I need to finish gluing up my rear DV46 so I can swap and see if it persists.
As far as lubing, lube the area where the spring inserts into the arm? Anywhere else? Should Triflow do the trick?
I haven't received my Gravitas yet so I can't talk from experience but I used to take my zero gravity completely apart and clean and lube them with waterproof grease and it always freed and quiet them up.
