My SI is drilled 2L as well. It is not nearly as strong as some people say. It works well on second shift lanes with dry back ends. My first shift lanes have me using the Paradigm. On second shift, I pull out the Smokin since the backend is drier on that set of lanes. But should the SI fail, I pull out the Paradigm since that is my Fail-safe ball.......sorta.
