Creton is extremely good in 109s, and yucca or blukitty pwn anyone in uber flapped allied rides. Leviathn or sniper would be the choice in a spitfire, and KillnU and his whole squad pwn everyone in P38s.
there are also some fantastic talents in the H2H rooms.
I got totaly kicked by a guy named DocUewe in the jellycross teams server, he in 109f, me in P47D25, although pwning me isnt hard.
some other names to look out for will become very apparent after a month in the MA.
