Seems to be the trend with a few tour series molds changing from swirly star to Halo so far (Wraith '19 Walker -> '21 Gurthie, Destroyer '20 -> '21 Heimburg, and Leopard3 '20 Fajkus -> '21 Scoggins) for 2021. Each of those had a non-tour series run in 2020.
Other swirly star tour series from the past few years were the Koling Thunderbird, Barsby Eagle, '20 Walker TL3, '19 Gurthie Wombat3
Remaining Innova Star team members with TS discs - 2020 and prior :
Sexton (USDGC) - CG Firebird, Nexus Firefly, Stock Signature Star XCalibur new for '21
Koling - Swirly Thunderbird
Salonen - Star Destroyer '20, Star Aviar3 '19
Bloomros - Luster Ch. Roc3
Barsby (1x WC) - Swirly Eagle, Stock Signature Star Roadrunner
Wysocki (2x WC) - Galactic KC Pro Aviar, Pro Pig, Stock Signature Ch. Teebird3 & Star Destroyer
Valerie Mandujano already took the Galactic Pro Aviar Driver for '21 so Ricky will be switching one of his. Innova has done generic team TS Pro Roc3 and Aviar P&A the past couple years so maybe one or more of the remaining will take those. Could see one or both of the FPO players choose the Halo Shryke/Valkyrie/TL3/Roadrunner. Champion team did have 2 different TS Shryke variants already though.
Could see Barsby switch the Eagle plastic (Glow or CG, Luster?) or a different mold entirely since he hasn't been enthusiastic with the swirly star Eagles so far (still working in the first 2019 ones in 2020).
