Okay guys, a question. I've been using the double willow blade harnesses in watermelon and purple,black. Are these the right pick or should I be using something smaller with a single blade? Also, what speed are you all trolling at? I spend 6 hours trolling today on Meyers at 1.5 to 2 mph on lead core and 30 jets. Marked them but didn't get any hits. Was really frustrating. Starting to think I'm jinxed!
