Whatever it takes!!!
You already got that one in Root and maybe if you play Bethell at 4, then him as well.Two of England's top seven need to bowl a minimum of ten overs per innings between them. If Curran is at seven then you need some reliable bowling elsewhere. Not sure about Bethell or even Brook as three format players tbh.
I don't mind the idea of Billings and Curran at 6-7 with five solid batters, one of whom must be able to bowl.
Brook
Duckett
Root
Bethell
Buttler
Billings
Curran
Archer

Mahmood
3rd seamer/2nd spinner depending on pitch
