Ok,
Used 180 grit sandpaper to try and resurface the pad then tried to re-bed them. Put another 25 miles on it and the front brakes still scream/grind like a banshee. I am going to install the ICE rotor on the front for now (only have one set of new avid pads) and see how it goes.

On a similar note, since the cannondale is setup for disc/v-brake would it be prudent/is it possible to add a stoker controlled V-brake
