Swissstop Yellow King vs Black Prince

[cgolvin]

Which do you prefer and why?

According to their site Black is superior in modulation, inferior in stopping power and longevity. Personally, I care most about stopping power. Using Black Prince with BTLOS rims and, while better than my experience with previous carbon rims, I still have to think more about braking during fast descents than I do on aluminum rims.

Or should I just buy Campy red instead?
