Hero disc type 235 is a little confusing to me. The sonic, super hero and super sonic are all marked hero 235. The sonic and super sonic are both too small and the super hero is slightly larger. Is the only hero disc approved for superclass the type 235 with the superclass stamp on the top or is the super hero also legal? I think more distinction should be made between type 235 and discs made based on the 235 mold.
