Dont get me wrong, Im going to do it less often now for sure... only when I have to! Nothing else has been able to clean up a cruddy, black atty.
Doing it because you have to, is different than doing as "preventive" maintenance. Some folks (a good majority) do it (preventive maintenance) to extend their life, which has the opposite effect. I found that popping an under performing atty to HV, will give it new life, and that life is often quite a duration.
