It's a grip issue. Smooth edges will not grip the Amsteel and the knot will slip against itself in the half hitch causing the advanced wear problem. As far as a solid braid dyneema, I haven't found a use for any. The second version of Speed Hooks will be out soon, but in the meantime, I'm using my hooks as Whoopie Hooks and they work fine. Just have to make sure the continuous loops are fully seated in the hook.
