Fishy,
What are you using? Have you considered other tackle? I am pretty sure you have, as you have voiced your concern here, but I still would like to hear.

Overall, do you think a single Siwash 5/0 or 6/0 causes less damage than a herring rig? I have hootchy rigs set up both ways. Even being able to keep both clipped or unclipped in 9/10 I haven't killed 25
