Drex and Fester are the first ones that I thought of. I think Fest was also Citabria ( spelling?)
That's my memory as well-the Fester being Citabria thing that is.
I remember Drex being unbeatable in Warbirds. Then he and Levi (aka +Dead, DeadF, +todd, Todd, Uber, Levi amongst others in AW) joined forces in the Blue Knights over here. Sheesh, what a talent pool that squad possessed. they were/are all bona fide killers.
I also kinda think Fester/Citabria was the phenom that was -ASF- (Altitude Super Freak) back in AW. ASF absolutely crushed it for a few months in 1995/96 and then abruptly left. I could be wildly wrong but just a hunch.
