Most of my days I have used Berkley Trilene XL. This fall started playing with Suffix, both the hi vis yellow and orange.
Was concerned it might spook the crappie since I mostly fish Green and it can get pretty clear, but it hasn't. I have used it on bright sunny days at the same time use green line with the same jig to see if it affects the bite and it did not.
My personal opinion, I don't believe crappie are as line shy as some other species. Just my opinion.
