Default Propellers

I notice that Hartzell and MT only have 200 hp recommendations on the Vans site.
For those flying or have researched the right prop for the 210hp can you post your recommendation please.
Thanks

Would it fair and reasonable to think that the propellers used for a O-360 would be where I would select a suitable propeller the -390 from?
My understanding in flight would be the propeller would run slightly coarser than a -360 for the same manifold and rpm selected on a -390 compared to a -360.
Am I on the right track here?
Thanks
