When I was in the Alps earlier in the year, I noticed that my pads were a bit worn and bought some new ones - I only had a choice of either Swiss Stops or some very cheap ones already in cassettes,
I opted for the 26 euro Swiss Stops all weather pads and have to say that I noticed a marked improvement over the Dura ace pads they replaced, particularly in the wet.
When the pads wear out in the 105 brakes I have on my commuting bike, I'll definitely get something as good as the Swiss Stops, I like being confident in my braking power, especially in the wet.
