I'm in the camp that prefers Star to Champ in my Eagles. It seems that Star has better glide and doesn't have as much fade at the end of the flight, but it may be that Star breaks in a bit faster. I also generally shy away from the L mold. On the whole, though, I believe there's no such thing as a bad Eagle. Pretty much every X mold I've ever thrown flew like an Eagle-X when it was brand new, no matter if it was DX, Star, or Champ. The DX just breaks in way faster, but a good cycle of Eagles is awesome.
