Question for Roto Grip users. Going to the Nationals in about 3 weeks and I am trying to decide what I am going to take. I have two SD-73s drilled and I was wondering how anyone has faired using theirs at the tournament? I have decided on taking my Neptune, Mystic and spare ball. Trying to decide on whether to take the SDs, Secret Agent or a few other solid balls. Any input is welcome. Thanks!!
