Brought in a 50lb spoonbill one night without too many problems (surf pole with 50lb test). The next one I hooked spooled me and popped the line when it got down to nothing. Sounded like a .22 going off. Never saw it but the weight and power was like nothing I've ever felt before... or since. Wish it would have surfaced just once to get a look.
They make 200# Spectra that is used for the big tuna with a top shot of 175 mono. That'd stop them from spooling ya!
