Keeping the faith in the Woryna deal, Has to be some logic attached to Tobi's departure rather than GSA related because King won't be able to cut the mustard @ No.5.
Letting Musielak go for an extra 0.50 to use in the engine room wouldn't make much sense tbh because Doyle would effectively be in 2 v 1 races when it comes to Heats 13 & 15.
I'd be shocked if the Top 4 isn't Doyle, Woryna, King and Brennan at this point.
