You haven't told us what kind of rim you have. The green SwissStop pads are made for ceramic rims - which are very hard and will eat a less-dense brake-pad. And using the greenies on a typical alloy rim will result in excessive wear & tear to the braking surface.

I'd give the Kool Stop salmon brake-pads and see what they say. Oh - do you have any pictures of your rims and brakes?
