You're mistaken and stubborn, deaf or listening to retards... I couldn't care less which. MLS (Multi-Layer Steel of which there are a few different types), graphite composite aka just composite (which have a steel shim as a base), asbestos, and single layer copper are all TYPES of HG. COMETIC is a manufacturer of HGs; The only HG they make for the 7M is MLS and it also happens to be the most forgiving of higher surface roughness.
There's no such thing as a cosmetic HG; Unless you think a single layer copper, shim type is nice and purdy (which they are when new). If you'd search Google a bit you'll find that the results which aren't automatically corrected to "Cometic" are generally forum discussions in which the person is corrected in short order.
And we're not trolling... we're trying to ensure that information posted is as accurate as possible.
