For smallies 8 pound Trilene Sensa Thin in low vis green was always my favorite. I don't know about the fish, but I don't see it well anymore, so I have been trying lines that I can see better. I always have a snap on the end so I do not have to retie constantly. I have never switched because of water clarity. I try to keep it simple. I cannot say if it makes a dif. I still catch fish.
