Default 36' Concept, Prop Question ?

I have a 36' with twin 300 Verado's

The Boat arrived with Three Blades from the factory, 21" Vented with 1/2"holes.

It comes out of the hole and on plane very quickly, hits 6400 rpms @60mph. with no tab adjustment and very little trim.

What other props have worked well with this application ?

Thanks in advance
