After testing hi viz ( which I love due to bad eyes, and being a crappie troller ) Trilene Big Game green mono , and fluorocarbon in a clear water state lake that I regularly fish for monster shellcracker.... It took no time to realize that Clear fluorocarbon was catching more fish. I will say I have noticed no difference in catch rate in muddy water. But this particular lake is spring fed and clear by Mississippi standards. I am reluctant to reveal this , cause I know some on this thread are targeting the same fish as I am. I just hope they remember to share a tip with me at some point ��
