i have had success using the MANN stretch 25 and stretch 18 lipped plugs , i have caught yellowfin while slow trolling. one thing i would recommend is to remove the two treble hooks and replace them with one single hook at the rear.i have NOT had a missed strike using the single hook.i have also has luck wirh albacore on the bonita and braid plugs ,again removing the two double hooks and replacing them with a single hook at the rear.it is too dangerous bringing a thrashing tuna into the boat with several treble hooks hanging from it's mouth.but i have had good success with plugs trolled slow.i usually put them in a pattern while i am using ballyhoo.i have had fish hit both the plugs and the bally at the same time.
good luck.
good luck.
