I fully understand this rig and am excited to fish it. I'm getting ready to fish Lake El Salto in Mexico in a few weeks and want to try this rig. My concern is hooking up with a hawg on the upper leader rig. It seems like the direct pressure from the free running swivel up and down the line might cut the line, especially if you're fighting a double. Is this ever a problem? I plan to spool up with 20-25 pound Big Game line.
