I myself have not had good luck with O.S. plugs. I know, I am told they are the best of the best. They have not worked well for me. If I have a rich low end or mid range I go with an Enya #3. They are the best plugs I have had. I have also had good luck with Fox Miracle plugs. The cheaper Hobby People Thunder bolt plugs work pretty well too.
