How do you decide double vs single porosity for simulation model?

If we are dealing with moderate permeability reservoir 10-200mD and have only few fractures observed in core how do you decide if it warrants double porosity or single porosity is sufficient for simulation modelling ?

There were only few sub-economic wells were drilled, they did not have any rapid WCT breakthroughs. Productivity wise to match wells production we may just use high side of poro-perm transform so making double porosity/perm model might not increase productivity significantly unless we assume more heavily fractured reservoir with large shape factor which might be difficult to justify.
