These are the Fishing Addiction Gear Perch Fly Rigs! Lots of time on the water and product development have gone into these rigs. From the line used to the lead lengths, it's all been done for a reason. Over time we have continued to improve and strengthen the rigs. Each rig is tested for quality and strength throughout our manufacturing process. Our latest version is our strongest yet. Big water perch fishing requires a stronger rig to hold up to the occasional non target species such as sheepshead and catfish and that's why we continued to make them as strong as possible. Each fly hangs away from the line to "float" in the water. Tip with a whole minnow, chunk of minnow or any other live bait. These can be used for any type of panfish, not just perch. They also work great for crappie and bluegill! Sold per each. See our Facebook page for current perch reports and to see these perch fly rigs SLAM some jumbo perch!
