In reply to Webster:
looking at the Quad and Nomic pick, the Nomic pick will fit the old type 2010 Quark. You will have to file less than a mm off the internal corner of the hammer where it meets central hole of the Nomic pick as the profiles within the head are not quite the same. You will also need a 0.5 mm washer as the cuts in the picks are different depths, the Nomic is deeper.
Very simple job. Of course the teeth on the pick end a little sooner at the head so will look a little different.
