That's a great deal.
I'm running CX70's in my cross bike. At first, I thought they were just OK and they squealed like mad. This season I was determined to get better (and quieter) braking, so I ditched the interrupter levers, switched to Kool Stop salmon pads and installed Jagwire Ripcord housing. I don't know which change made the biggest difference, but with this combination the braking power is outstanding. Even with these changes it took a lot of fine tuning of the toe-in to get rid of the squeal, but that's gone too now.
