I was lucky enough to run into Joe "TwisteD FlyeR" Rotan as he was driving back to OK from OR on NY'sEve. He gave me a Pro and Champion TF Destroyer. After a little field testing, I'd have to say that the Pro is less overstable than the Champ or the *. The Pro stayed in the air the longest for my rubber arm, too. The champ was longer than my * also. The star D is a first run os pig. I like the lighter CH and Pro better. They don't tear my 50-year-old arm off like the star does in the colder weather. Thanks again Joe for the unexpected equipment. Great seeing you and Danielle.
