I've hand 8 or so Champ and colorglow Champ Shrykes, and at least that many Star. No GStar as I don't really like that plastic.
Mine have been fairly consistent in dome shape and flight across all my samples. Stars have been a little lower dome and noticeably less overstable finish than the Champs. I can get a lot of turn and very little LSS finish on the Stars if I lay into them.
My Champs are all a little more domey than the Stars but not pop top. A fresh one thrown flat will fly virtually straight for 80% if it's flight and have a gentle hyzer finish. If I throw it with a shallow smooth hyzer it will hold it throughout.
