I've had a few I've regularly winged with since I started this madness in 2005, but I think my favorites are:
Stimpy from the (now-disbanded) Rogue Griffons - a co-worker and friend who shared a love for all things warbird related. He pulled me into AH from IL2 and Falcon 4 multi-player land to the Griffons where I few for several years as Hoplite. Not only a decent stick and good teacher, but maybe the most hilarious person I've ever known. I wish I could get him to come back to the game but he's too busy now working for Lockheed-Martin.
AKPepprr of the Arabian Knights - As Changeup said in a previous post..... "No Fear". She dives headfirst into some of the craziest fights I've ever seen and she laughs with glee pretty much the whole time. She's a blast to fly with and has good SA...much better than mine (tho' truth be told that's no great feat). Most of the fights don't end well...but they are always guaranteed to be interesting!
That reminds me....I would like to set the record straight: Despite claims by Pep....I do not use her as "bait".
...
Well....maybe sometimes.
