Base sizes of Daemons from the Ruinstorm

[Deus_Ex_Machina]

As the title says. What kind of base sizes would you use for the following models:

 

- Sovereign & Behemoth (Monstrous, W7, Bulky 7)

- Hierarch (W4, Bulky 5)

- Harbringer (W3)

- Brutes (W3, Bulky 3)

- Beast (W5)

- Arch-Daemon (Monstrous, W8, Bulky 9)

Beast bike-size, Brutes terminator size. But no Idea for the rest.

There is also daemonic cavalry in the army list which I didn´t present in my original post. So I would use bike sizes for them. It is strange that GW didn´t make the effort to add the Bulky trait to all entries in order to give the hobbyist a faint idea of what to expect from the models. And yes, Brutes on round 40mm makes sense.
