I have the standard gloss black hugger; I plan on painting it Grey. The standard hugger is made of fiberglass. The carbon hugger does look nice, but since I'm painting it, no reason to buy the carbon. I will post a picture after I paint it.
You don't have to drill any holes with the NWS hugger. The left side attaches to the swing arm with the same holes that were used for the chain guard. The right side uses a bracket that connects to the right spool tap.
