I'll list the guys that, after first pass I KNOW I'm up against a dangerous opponent.These same guys not only beat me more often than not,but are 'good winners' also.These are the guys that keep me coming back for more,win or lose.Sometimes I get so caught up watching thier gracefull moves,that I forget that I'm in a 'do or die'situation.

Of course,I am swiftly prosecuted for the lapse!
Kieren-great pilot and gentleman
Mighty-same as above-good gene pool I suppose

EZ-This guy flys BnZ type planes more agressively than most fly Spits!
Camel-only had the pleasure a short while in beta,but the memory lingers

Fishu-(for a 190 driver,this guy took me to school in my own angle-fighting game.
Cavalier-beats me at my own game.
Racerx-ditto
Rod-ditto
Hblair-requires no explanation

Udie-have only flown against a couple times but it was immediately made clear to me I was about to perish!
All told,as an Ex-Warbird pilot,I am still amazed at the VERY high skill level of even the avg.pilots in AH.We have logged some SERIOUS hours of combat time!
There are many other great sticks out there,this is just my 'shortlist'of the ones that have burned themselves into my recall

Salute all that share this passion of mine.
