Take a look at the damage and notice how it gets progressively worse as you move in. The larger the sprocket, the deeper the gouges, until you get to where sprockets are paired on aluminum "hubs" or spiders. The wider engagement area of the spider doesn't damage the freehub body, despite the sprocket having more torque. This is the best evidence of the superiority of having larger sprockets on spiders, vs. all loose sprockets and spacers.
