I'd also avoid any without specific holes (or slots like the Atom 440s). I would be wary of any of the Atoms, nice though they may look; some of the 600's were not rebuildable, and they often needed it; the cones are too thin near the edge of the race and bits break off. I haven't checked a set of 440s to see if they have the same cones.
