AFAIK there is no control tyre for the SE Region.
Given the amount of rainfall we've had recently, I'd say anything that floats might be worth a punt
Seriously - Schuey Yellows have always been a safe bet if its dry - though the track might turn towards a green or a silver later on.
BB minispike Greens will feel safe - especially whilst there is grass on the track but if the surface gets stripped, they might begin to struggle although if it's wet, they might be a better all round tyre???
I ran Losi Silvers there last year in 2WD (yes they are commercially available) and whilst the bump absorption was first class, they lacked the sidebite that a Schuey tyre offered so ultimately, there was very little in it in terms of actual pace.
Much will depend on what the rain gods choose to do between now and Sunday I fear
