I would say UN but you limited it to iServer's only 
so I'd say Classic just because of the wide variety of hats and hat styles they have had over the years, and continue to have
the rest of the servers main attractions aren't hats like Classic too so that also explains a bit |
UN?? Are u joking. Lol. It's a ******ed version of classics graphics and on top of that they just edit other servers' hats
