I've been tangled in mono and braid fishing line, braid is worse, trilobite line cutters work great for both though. Also been wrapped up in a shrimp net hanging of a sunken shrimp boat in Pensacola bay with almost zero visibility. Used my BFK to free myself and then free a HUGE redfish that swam under the net. When he started banging into me I had no idea what type of monster was after me. We're both ok.
