I fished that same area on Saturday and had two breakoffs on large fish. Didnt get them close enough to the boat to see what they were. The first somehow managed to stretch the wire out on an interlocking ball bearing swivel. On the second, I had a clean break on my 14lb XT mono leader. We did catch some large cats near Gull, so not sure if it was another Catfish or perhaps something else. All I know is it fought like hell. Didnt feel like the dead weight of a Sheephead either. You didnt happen to find a Purple Reef Runner 600 Little Ripper in that Muskie's mouth did you? lol.... Whatever stretched out my swivel stole my brand nee lure the kids got me for Fathers Day....lol
