if this is for YOUR cue, you shouldn't be asking for someone else's advice. you're the one who's going to live with it.
the choice of design may depend on where it goes. will it inlay into points,,,,windows,,,,or will it float in a large empty area. will it be inlayed singley or clustered with other inlays. will it work large or small?
one inlay looks like a "thing",,,one inlay is a car logo. do you want that reaction? one inlay, imo, would look better in an alternate design. a couple might look better with a mix of two different materials.
