I have a few questions on worm harnesses. I have been trolling spoons with 40tt jets and did not have any luck Saturday --why I don't know--I was trolling 35,40,45,50 back at 2.0mph--worked great the week before but no dice this last week. Anyway how fast would I troll with a harness? what size blade is best? what kind of harness --how long? any help on catching these walleye will be greatly appreciated Thank You!!
