I've tried different pads, brakes, and even a different fork (went from the default Surly Cross-Check fork to a Nashbar/Winwood carbon disc fork). It must have something to do with my rim (Velocity Dyad). The rear is always whisper quiet though.

Check out the
Gunnar Rock Tour. From the pictures it looks like it needs a suspension-corrected fork though. There's also the Rock Hound and Rock Hound 29'er, but from the pictures it looks like they don't have the rack-friendly caliper mount.
I had the exact same problem with a set of Avid 4 cantis on my JTS (which had open sport rims). I switched to a DT brake pad set and that helped a little, but they still squealed like mad in some conditions. In rain people looked around for the truck.
