I throw...a lot of stuff. I basically want to throw everything I can....just to see. With that said...here goes. I'll try to note where I throw something a lot, or have only tried a little...as that might point to where I just got a whacky run.
2x Star Destroyers - 1 old and flippy, 1 new & more overstable. To me this would be a Nuke (ESP, very similar to a Star Destroyer in my opinion) and a Big Z Zeus...the Big Z Zeus is decidedly more flippy than a Big Z Nuke. There are other random runs of Nuke that could fit this slot...but my goal for you is currently-produced stuff, not a hunt for old runs. I throw Destroyers a bit...but Nukes a LOT.
3x Teebirds - 2 champ that I can throw for hyzers/flips and "straight" shots, 1 star that I use for left to right turnovers. Probably something like a Stalker. 7 speeds aren't my thing much...but I've thrown both a Stalker and a Teebird and they seemed very similar. A Passion likely fits this spot as well.
2x Leopard3's - both for slower anhyzers/hyzer flips. Slightly faster than a Leo3, but a Heat fits this pretty well IMO. Stings fit in this pretty nicely too. Most of my fairways are 9-speeds, I throw Heats a lot for hyzerflips.
