Fished that area numerous times with the Late Great Ed Martin. 20 fish days if you had the stamina....lol. Ed loved to run a tight spread (7 - 8) on one side of the boat.... leaving the other easy side to turn to upon hookup.....leaving multiple lines to "fall" together on the trailing side. Best "hookup" on a single troll bite.... six stripies on .. .. ALL rods bit.....in less than 60 seconds. Controlled pandemonium. It was wonderous!!
And your right....I believe the competition and bait supply down there makes those marlin act "stupid".
