I think the CBR guys are going for a look more than anything else. I like a 5 or 6 spoke wheel over a 3 spoke from a fashion standpoint. If the 3 are lighter and you are going to track the rc then go for it if not why bother? Personaly I prefer a y spoke style wheel carozzeria or pvm to be specific.
