A:
I have been using it for several months now. Because its a co-polymer with fluorocarbon coating it does sink, not as fast as a 100% fluoro but it is very strong line. I picked up a 35 pound river rock cause my lure got stuck and the line didn't break, or even so much as stretch. If you have been using mono lines more and are trying this out for the first time, the sink rate is still almost twice as fast because the line does sink.
