If you can get a RIS then it is a huge boost, particularly in poor VMC and it is your only protection in IMC.
We were talking VMC here....IMC is a different story. I don't object to anyone turning on the radio, I just think it is only an aid, and not always that useful. Anyway, as I don't have a transponder I don't ask for radar service, it only increases the controller's workload for a dubious benefit to me and others.
