It might just be me, but it looks like the rim doesn't have a machined braking surface. If that's the case, getting kool stop pads may not have the drastic increase that you are looking for. I know that I had a bike with rims like that, and it was just stupid. Maybe once the paint/ano wears off, the braking will be better.

In any case, I have salmon and black, but ride only in the dry, so I've only used the black. The salmon pads are just sitting waiting for the blacks to wear out.
