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. 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. Features: Each rig is tested for quality and strength Each fly hangs away from the line to "float" in the water Size 4 hooks Pair these with our Clip on Flies to add a third hook
