For a video game activity, I offer two short pages featuring two different images of the same map, but with different routes, satisfying different priorities. The small textes explain the pros and cons of each route. They are organized in a four pages cluster.

a) Google CANNOT predict which map fits the user best.
b) The search requests are NOT specific enough to target a specific map

In this situation I think the cannibalization risks trumps the seo benefit of the fourth page. Therefore I am encline to use noindex. What is your opinion?
