OP here...soo I've got in some throws with the discs I ordered:
GStar Teebird - Pretty much just held a pure hyzer and didn't flip up at all.
Star TL, Champ TL - these didn't like to hyzer-flip much if at all, and when they did, it was not really to a flat/straight path. It was a hyzer-flip to a slightly less hyzer, and a healthy fading finish. Even on an anhyzer line I didn't like how they faded back left at the end. It did good flex shots on different lines, but that's not what I'm after. I want something that will finish straighter.
Stiff Vamp - I liked this one the most, but it was actually a little too understable. On a 30 degree hyzer it would flatten out, turn over a bit, and drift right for the latter half of its flight. At 45 degrees it would flip up to flat and fly super-straight with practically no fade. It was a little too understable for a true anhyzer line as it never wants to flatten out and holds the anhyzer all the way to the ground where it lands on edge.
So it appears I'm looking for something between the TL and the Vamp- something that I can throw on a 15-30 degree hyzer and it will fly like the Vamp did on a 45 degree hyzer. And I'd like to be able to throw a fairly high anhyzer (maybe not quite sky-anny) and have it flatten out at the end for extra distance instead of fading back left like the TL's or not pulling out of the anhyzer at all and landing on edge like the Vamp
