black/salmon kool stop pads for shimano brakes

i've tried the black kool stops, the salmon kool stops, the black/salmon kool stops (which i'm using now) and the black swiss stops. out of all those, i liked the salmon kool stops the best, cause they're easy to clean and maintain and stop really good in both wet and dry. i hated the swiss stops the most, cause i used to always see metal filings in the pads when i would take the wheels off to clean them, and that started leaving marks on the wheels, which never happened with any of the kool stops. i never tried the purple swiss stops..
