Richie,
SwissStop blue - in the dry they were the best ever, in the very wet not so good for me.
I think they were set up right, no squealing or judders, blocks met the rims squarely.
Went to the dark side - Koolstop CSS (black).
I find them better in the very wet, not as extremely good in the dry, softer feel when in use.
Julian.
